Testo completoAbstract (sommario):
Aircraft noise is one of the serious environmental noises with the increased use of flight traffic. The purpose of this study is to understand aircraft noise levels of airport communities in Korea using baseline data for audiologic management. Aircraft noise levels were retrieved from the National Noise Information System every month between 2004 and 2018. We reviewed aircraft noise levels obtained from total of 111 airport communities across 14 airports. In order to understand aircraft noise levels of civil and military airports, the aircraft noise levels measured in civil and military airport communities compared with the noise levels from civil airport communities. The data showed average 71-73 weight equivalent continuous perceived noise level (WECPNL) for fifteen years across airport cities and the average noise levels did not increase over time between 2004 and 2018 years. The civil and military airports showed about 12 WECPNLs of increased noise levels compared to the civil airports. The most civil and military airport communities, including Gwangju, Gunsan, Daegu, Wonju, and Cheongju generated the maximum noise levels and ranked as the highest airport for aircraft noise levels. Although aircraft noise levels in airport communities were similar over the past decade, civil and military airports generated increased noised levels compared to civil airports due to jet plane noises and other military-related noises. Careful consideration is necessary to implement noise reduction policy for civil and military airport communities. Ongoing noise control, hearing monitoring, education, and relevant policies are required to improve the quality of life in the airport community residences.

The current study presents the analysis of seven airport exemplification case studies undertaken in the European project "Aviation Noise Impact Management through Novel Approaches - ANIMA". Best practices related to aircraft noise management at airports in individual airport contexts were implemented and evaluated. Case studies on communication and community engagement in airport noise management were investigated at Heathrow (Great Britain), Ljubljana (Slovenia) and Rotterdam The Hague (The Netherlands) airports. For Zaporizhzhia (Ukraine) and Iasi (Romania) airports, the implementation of interventions related to land use planning was examined. The interdependencies between noise and emissions were studied for Cluj (Romania) and Catania (Italy) airports. All case studies were performed under the scope of the corresponding national legislation and guidelines. Individual characteristics of airport operations were taken into account. The case studies were aligned with expectations and priorities of all involved stakeholders, such as representatives of airport operators, local communities, civil aviation authorities and policy makers. The efficacy of the noise management case studies is assessed in terms of: the capacity to negotiate consensus outcomes, the extent to which noise impact reductions were achieved; and the participants' satisfaction with the process and outcomes. Experience gained from these studies will be used to distill best practices for future intervention.

Airports in Poland are obliged to observe the sustainable development principle and therefore to reduce their environmental impact by creating so-called limited use areas (LUA) related to aircraft-generated noise. The research authors analyzed airports’ impact on the prices of single-family homes located in the vicinity of airports. The LUA is therefore defined as the area designated to study the airport’s specific impact on the single-family housing market. This is a formal limit which determines the examination of price changes and the decision-making conditions of market participants. This methodical approach is justified because no excessive noise is expected outside the LUA. Therefore, two markets in the vicinity of airports were examined. One is in an LUA which is closer to the airport, and the other market is outside the LUA where external noise effects are not present. Thus, we consider that real estate located outside the LUA is not subject to a significant negative impact from the airport. The study covered the Gdańsk Lech Walesa Airport and the Warsaw Chopin Airport in Poland in adjacent areas with the research time horizon of 2013–2017. The study examined single-family house prices. We used a time series analysis, a classic multiple regression model, a spatial autoregressive model, and geographically weighted regression models in our research. Additionally, Geographical Information System (GIS) tools were used to visualize the results of our study. The research result was to demonstrate different impact levels of airports on the prices of single-family houses located in limited-use areas in Gdańsk and Warsaw. This research carries significant implications for the general public and airports’ economic decisions in resolving conflicts between the airport and residential property owners in airports’ vicinities.

Various noise measurement parameters/indices used to define aircraft and airport noise are explained. The noise zone limits used around airports in some countries are given. Noise prediction software can be used to generate noise contours around airports. New aircraft noise certification standards have been developed to encourage control of aircraft noise at source. Aircraft noise can also be reduced if noise abatement landing and take-off procedures are followed.

Before the opening of the new Munich International Airport and the termination of the old airport, children near both sites were recruited into aircraft-noise groups (aircraft noise at present or pending) and control groups with no aircraft noise (closely matched for socioeconomic status). A total of 326 children (mean age = 10.4 years) took part in three data-collection waves, one before and two after the switch-over of the airports. After the switch, long-term memory and reading were impaired in the noise group at the new airport. and improved in the formerly noise-exposed group at the old airport. Short-term memory also improved in the latter group after the old airport was closed. At the new airport, speech perception was impaired in the newly noise-exposed group. Mediational analyses suggest that poorer reading was not mediated by speech perception, and that impaired recall was in part mediated by reading.

Major issues and statistical data of the noise impact created by air transport, namely civil aviation aircraft, are analyzed. The main methods of reducing aircraft noise are considered. One of the methods of noise control and mitigation near the airports, namely ‘noise contour calculations’, is proposed for consideration. The description of the calculation method used and the calculation of the noise contours of the civil aviation airport are given. The civil aviation airport of one of the largest cities in Russia was chosen as a subject of research. As a result, maps of noise contours around the airport were obtained and information about the benefits of the data was provided.

The motivation behind this research was to analyse the consequences of aircraft operations’ delays on cumulative noise levels produced upon the neighbouring communities and to estimate the relative change in the number of people annoyed by aircraft noise. Many studies showed that residents’ reactions to abrupt changes in noise exposure were more intense compared to the anticipated ones. Aircraft delays may cause such abrupt changes in noise exposure by increasing the traffic in some periods compared to the scheduled traffic. The methodology applied includes noise contour development for two different scenarios for intervals where aircraft delays occur. Only delays connected with the Total Airport Management (TAM) were analysed, since such delays can be influenced by airports. The first scenario considered the influence of aircraft operations on population noise exposure without TAM delays, whereas the second one included all delayed flights (actual traffic). The proposed method was tested through case studies of three southeast European airports. The results showed that the highest potential of decrease in the number of people annoyed by the noise was recorded at Niš Airport (59%), followed by Zadar Airport (49%) and Sarajevo Airport (25%). Similar results were obtained in the context of highly annoyed people.

Abstract This paper describes an optimisation study concerning arrival trajectories that has been conducted using a recently developed tool for the analysis and design of noise abatement procedures around airports. This new tool combines a noise model, a geographic information system, and a dynamic trajectory optimisation algorithm. The optimisation algorithm generates routings and flight-paths that minimise the noise impact in the residential communities surrounding the airport, while satisfying all imposed operational and safety constraints. The study on arrival trajectories presented herein complements an earlier study involving departure trajectories. Although the numerical results shown pertain to a particular example airport, viz Amsterdam Airport Schiphol, the study actually focuses on the development of a generic methodology that could be applied to any given airport. The results clearly demonstrate the effectiveness and flexibility of the developed tool.

Testo completoAbstract (sommario):
The high noise level in modern airports is one of the causes that affect the occurrence of accidents involving airliners and ground vehicles operating at the airport. In this study, an emergency prevention algorithm has been developed aiming at reducing the probability of an emergency collision of an airliner and a land vehicle by separating the noise generated during the airport operation into the noise that warns the pilot (operator) about the threat of an emergency collision and the noise that contributes to the accident initiation. The results of the study can be used in the development of new methods and technical means aimed at preventing accidents at airports.

Airport noise is noise pollution produced by any aircraft or its components, during various phases of a flight,especially the landing phases. This paper study the airport noise prediction model basing on WECPNL(Weighted Equivalent Continuous Perceive Noise Level) recommended by ICAO as a index. With the measurement data,which is properly distribute to the final of active runway and centerline, a brief summary of WECPNL-based prediction model from touchdown to runway centerline is established. However, the results showed a discrepancy of certain points was between prediction and measurement data, especially 1.5-2.5km away from the airport. Therefore, an amendment was proposed with greater accuracy, which the relative of the new model for future prediction ranged from 1.0% to 2.0%. To some extent, this model also can reflect and make full use of the limited data with a high accuracy, especially suit for monitoring rapidly in some new small airports.

Testo completoAbstract (sommario):
Сreation of noise exposure maps and airport noise compatibility programs are the basic steps in aircraft noise exposure and impact management in/around the airports, both of them are fundamental for aircraft noise zoning procedures. Noise reduction at source is also a strategic element of this management, and efficient implementation of quieter aircraft designs in operation provides closer distances of the boundaries of noise zones prohibited for residences to runway axis. These new conditions oblige the decision-makers, responsible for noise management, to be stricter with procedures for noise zones definition and to include in consideration a number of new acoustic sources inside the aerodrome besides the aircraft in flight operation, which may influence the overall exposure and impact of noise on population living or/and acting around the airport. In other words, current noise exposure maps and airport noise compatibility programs must include these dominant noise sources at specific locations of the airport also, not only the flight noise sources, as it was enough before. Today such essential noise sources for consideration in airport noise management are the aircraft in maintenance and overhaul and the aircraft during the taxing between the runway and stands on apron first of all, especially if their locations are quite far from aircraft flight operation routes and close to the residential areas around the aerodrome. The noise maps are required to be calculated currently, as for aircraft operation, so as for their maintenance and overhaul, but the measurements are evident also for their confidence and accuracy purposes.

"Study on the ground attenuation of engine run-up and APU noise for developing the airport noise model in Japan". INTER-NOISE and NOISE-CON Congress and Conference Proceedings 265, n. 3 (1 febbraio 2023): 4374–81. http://dx.doi.org/10.3397/in_2022_0627.
Testo completoAbstract (sommario):
The correction for ground effect around airports is modeled based on the results of numerical analysis in order to make it possible to estimate the propagation of noise caused by ground operations in airports such as engine run-ups and APU to the vicinity of airports. The excess attenuation due to ground effects on sound caused by engine run-ups and APU is calculated using a PE method for typical jet aircraft and propeller aircraft, respectively. On the assumption that the ground around an airport consists of asphalt-paved surface and grass-covered surface in a certain ratio, the excess attenuation for the mixed impedance ground is calculated with the Fresnel-zone method using the results of PE calculation. The composition ratio of ground surface is assumed based on the composition ratio of asphalt-paved surface and grass-covered surface along the propagation path from the engine run-up spot to the airport site boundary of six major airports in Japan. In this paper, we introduce the excess attenuation calculated with the PE method and the correction model for ground effects on noise of engine run-ups and APU is discussed to implement it in the airport noise prediction model used in Japan.

AbstractThis study compares metrics for environmental noise diagnosis in schools at airport vicinity. The goal is to analyze and identify the most suitable criteria for scaling aircraft noise impact over schools, during landing and take-off operations. A Brazilian case study is conducted, based on the noise mapping and sound level verification. The day-night average noise level (DNL) and the time above limit (TA) are investigated using acoustic simulation and noise mapping and in order to identify the critical receivers. Results of DNL and TA for two schools at airport surroundings show that the criteria adopted by the municipal and airport authorities to describe the airport noise are unsatisfactory and do not reflect the intermittent behavior of this type of noise. It was verified that individual receiver analysis, based on noise interruptions thought TA parameter is more suitable for evaluation of noise impact over schools at airport vicinity.

Testo completoAbstract (sommario):
Before the outbreak of the Corona pandemic, Vietnam was one of the world's fastest-growing aviation markets. With the ambition that more than ninety percent of the population will have access to the airport within 100 km, the Vietnamese government approved developing the airport systems of 22 existing airports and six new airports. The rapid increase in air traffic in Vietnam has given rise to serious noise problems around airports. Preservation of the living environment for the areas around the airport was an urgent task to the Vietnamese government. Although the situation has entirely changed by the pandemic, environmental problems will be severe again as the aviation industry recovers. Therefore, a sustainable approach is to create a policy framework to prevent and decrease noise from air traffic parallelly with strengthening the air transport network. However, although Vietnam issued standards for general environmental noise, there had not been a legal and regulatory system that formed the basis of policies for aircraft noise. In this paper, the authors introduce Vietnam's viewpoints and efforts in developing the framework related to noise management around airports and discuss future issues and prospects. The authors summarize the activities that the Civil Aviation Authority of Vietnam has been working on with the support of Japanese experts for several years before the outbreak of Corona on noise policy development in Vietnam, including evaluation methods and monitoring technologies. These efforts have formed the basis for Vietnam's aviation noise policy.

Airports are required to manage noise impact owing to their requirement to obtain a social license to operate, and to comply with legislation such as the ICAO Balanced Approach and Environmental Noise Directive. Research has however shown that noise management actions and interventions often take a techno-centric approach, are implemented in silos, and that their success beyond noise metrics is rarely evaluated. Moreover, the success of Noise Action Plans in driving long-term noise management outcomes has also been critiqued at a number of levels. In the context of this background, this paper outlines the case for more strategic approaches to noise management and, drawing on the academic strategic literature, outlines approaches to developing such strategies that can be followed by airports. The aim of such approaches is to complement existing noise management guidance by providing step-processes that can aid airports in developing robust, repeatable, evaluable, and successful noise management strategies that are consistent with wider airport strategy and that are sympathetic to the needs of airport residents.

Most major airports use permanent noise and operations monitoring systems to reduce the noise of flight operations in the surrounding community. This paper aims at a technical proposal for a permanent environmental noise monitoring and control system to provide solutions to reduce the noise of flying activities for communities around the airport. Airport noise monitoring is often used to evaluate noise abatement programs and to improve the aircraft's take-off / landing procedures, to minimize the impact of aircraft noise based on altitude, flight path and time of day. Noise monitoring is usually linked to the tracking radar to determine which aircraft is in particular when the noise limit is exceeded and thus provides immediate operational requirements to meet. The airport noise enviromental monitoring and control system is often structured with fixed permanent noise monitoring stations, mobile noise monitoring stations, multi-parameter wheather stations, radar tracks and flights information to automatically evaluate the noise impact due to operation of aircrafts in the surrounds of airport, near and on residential areas. The entire system is operated by a software platform proposed as a cloud configuration available on the internet. The platform provides all the modules required to manage data such as noise and flight information monitoring and control, live data, reports, noise and flight information in public disclosure, complaints management, alarms and warnings, etc.

Testo completoAbstract (sommario):
The Debrecen International Airport has been undergoing a significant transformation regarding to the growth of traffic and its composition. Considering the dwelling zone location of the airport we cannot avoid the possible noise pollution that it may cause, since its permanency, and growth of intensity, could be the reason of durable health deficiency. The airports’ noise pollution zones are determined, and classified by domestic, and international regulations, the measured data of the noise monitoring system, and the content of the air traffic regarding to the type of planes. Summoning all of these we recommend the D zone qualification of the airport, and the traffic daylight restriction referring to the S5 type of planes. We also advise to build up a more sophisticated and wider extended noise monitoring system.

Purpose: On the topic of sustainable aviation a study was carried out to measure the difference between the actual change in air traffic noise and the airport’s residents’ perception of the noise change at Vienna International Airport. Therefore, a questionnaire was developed in cooperation with the airport and an online survey was conducted.Design/methodology/approach: For the survey of the opinion of the affected population of the surrounding communities, a web based online questionnaire is created and distributed via various channels including e-mail, and online forums. After the basic structure of the questionnaire had been defined, the questions were developed in cooperation with employees form the environmental department of VIE, who had a sustainable influence on the questions’ order and formulation. As the survey was supposed to be answered by residents around VIE.Findings: Results of the online study show that only parts of the participants are affected by air traffic noise at VIE. Even less experienced a significant change over the last five years. About one third of the participants stated that they are affected by air traffic noise in one way or another. The majority of these people live in Lower Austria, the federal state in which the airport is located. The participants obviously judge air traffic noise during day time more importantly than air traffic noise at night.Research limitations/implications: Due to the low number of returns, no statistically relevant conclusions can be drawn, the results of the survey can be used to make some general statements.Originality/value: Economic growth and deregulation lead to growing aircraft operations. Vienna International Airport with its approximately 260,000 flight movements per year is the biggest airport in Austria and a major hub in Europe. The combination of constantly growing air transport and the resulting noise exposure, as well as the steadily increasing sensitization of the population, bring the issue of aircraft noise emission into the increased interest of the stakeholder of an airport. The study compares the extent of the subjective perceived and the actual noise emissions’ change over the last years.

Yogyakarta International Airport is a new airport but for aircraft mobility operational activities it is very crowded and crowded. Therefore, noise is often heard from the airport due to the mobilization of aircraft taking off and landing. The noise can interfere with health if it passes the predetermined quality standards. The purpose of the study was to determine the level of noise concentration, to determine the effect of wind speed and temperature on the noise level in the apron area of Yogyakarta International Airport. To find out the noise level and other parameters that can affect noise, the writer uses the independent and dependent variable method. The independent variables are the type of aircraft, the value of temperature/temperature and wind speed. The dependent variable in this study is the noise value generated from take off and landing activities in the airside area of the airport with units of db using a sound level meter. From the results of descriptive statistical analysis, the maximum noise value is 97.7 Db and the average noise value during landing and take off is 93,512 dB and 92.80 Db. This value is still below the quality standard based on the IATA (International Air Transportation Association) document and the Decree of the Minister of Transportation No. 48 of 2002 concerning the operation of public airports. And the parameter value of temperature/temperature is 0.231 and the value of wind speed parameter is 0.089. This value has been tested for normality if the value is above 0.05 then the results are acceptable. This means that it explains that the temperature and wind speed do not affect the noise level at Yogyakarta International Airport. The possibilities that can physically affect the noise level are the pressure and speed of sound.

This paper aims at studying the problems of aviation noise and air, soil and water pollution in Tallinn Airport and the implementation of measures to make the airport more environmentally friendly. At present Tallinn Airport has two stationary noise level monitoring terminals and one mobile terminal for metering and modelling the noise level caused by aircraft taking-off and landing. Research shows that Tallinn Airport has not yet exceeded the noise limits stipulated by regulations. The area surrounding Tallinn Airport has been divided into four noise zones. Zone 1, where the noise level does not exceed 55 dB, is suitable for a majority of types of buildings, whereas Zone 4, where the noise level exceeds 70 dB and the highest level measured was 105 dB, is absolutely unacceptable as a building area. In recent years the number of flights flying over the residential areas of Tallinn has been reduced significantly, i.e. the number of flights taking off from runway 26 and landing on runway 08. In suitable weather conditions, noisy aircraft are directed to land on RWY 26 and take off from RWY08. Thanks to the measures mentioned above, air pollution from aircraft exhaust gases has been reduced considerably in Tallinn. After the completion of the military airfield at Ämari in the nearest future, it is going to be possible to transfer the cargo flights, usually made by large noisy jets, from Tallinn Airport to Ämari. Various measures have also been taken to reduce the pollution of soil and water within the area of Tallinn Airport.

As part of the agency's broader noise research program, the Federal Aviation Administration (FAA) has undertaken a multi-year research effort to quantify the impacts of aircraft noise exposure on communities around commercial service airports in the United States (U.S.). The overall goal of the study was to produce an updated and nationally representative civil aircraft dose-response curve; providing the relationship between annoyance and aircraft noise exposure around U.S. airport communities. To meet this goal, the FAA sponsored a research team to help design and conduct a national survey, known as the Neighborhood Environmental Survey (NES). Residents from households around 20 airports were selected for participation in the survey; the detailed sampling process is covered in another paper. Two survey instruments were administered to adult residents within the NES: a mail questionnaire and a follow-up telephone interview for the mail respondents. The mail survey was administered to samples of individuals in the selected airport communities in six separate "waves" over a 12-month period starting in October 2015. All mail survey respondents were invited to complete a follow-up telephone interview, which asked detailed questions on several areas including respondents' opinions on noise, exposure to aircraft noise, relationship to the airport, concerns about aircraft operations, views on airport community relations, among others. Analysis of the survey responses on annoyance levels and the associated DNL was used to estimate dose-response curves for each individual airport and a national dose-response curve. The national dose-response curve created from the mail questionnaire shows considerably more people are highly annoyed by aircraft noise at a given noise exposure level compared to historical FICON data. This paper provides a detailed discussion of the survey design and methodology. Additional information describing the motivation to conduct the NES and how its findings will help inform ongoing work to address aircraft noise concerns; and the noise methodology are provided in companion papers.

Abstract:This paper analyses impact of aircraft noise on community around Podgorica Airport, Montenegro. The airport is located 12 km from the city centre of the Montenegro capital, Podgorica. It served 1.3 million passengers and 7.5 thousand operations in 2019. The noise impact assessment is conducted in IMPACT web-based modelling platform using the distribution of operations by aircraft types, time of the day, and radar tracks for the busiest day (August 15) in 2019. Noise contours are assessed for Lden and Lnight indicators. They were merged with the Global Human Settlement Layer to assess the number of people exposed to different noise levels. In addition, based on the World Health Organization recommended exposure levels related to their health implications, the percentages of the population highly annoyed and highly sleep-disturbed are estimated. Furthermore, facilities of public importance (schools, hospitals, churches, etc.) are assessed against compatibility with the requirements set for the Zones with increased noise protection in national regulations. The results show that the exposure of community around Podgorica Airport to aircraft noise is still not a serious issue. The near vicinity of the airport is industrial zone and the number of people highly annoyed by noise is approximately 3.2% of the total city population. Nevertheless, it is crucial to draw attention to planners to preserve airport neighbourhood from potential inhabiting, to avoid problems that some airports in the region are facing nowadays.

Abstract sonAIR is a recently developed aircraft noise simulation model designed for single flight simulation while still being applicable for calculation of entire airport scenarios. This paper presents a rigorous validation exercise, wherein roughly 20’000 single flights were simulated using the 22 currently available sonAIR emission models of turbofan aircraft and compared against noise measurements. The measurements were recorded with the noise monitoring terminals at Zurich and Geneva airport, Switzerland, and with additional microphones installed by the author’s institution. Data from 22 measurement positions were analyzed, covering all departure and approach routes at distances from 1.8 to 53 kilometers from the airports. sonAIR was found to be accurate for departures and approaches under different operating conditions and aircraft configuration. The mean overall differences between simulation and measurements were well below ±1 dB in terms of noise event levels, with standard deviations of ±1.7 dB respectively ±2.4 dB, depending on the model type. A few aircraft types that displayed larger deviations are discussed individually. A sensitivity analysis on the input data found the quality and level of detail of the land cover data to be critical for the simulation accuracy. Changes in other input data such as atmospheric profiles and buildings had non-significant impacts.

In recent years, accompanied by economic growth, air transportation in Vietnam has rapidly risen with the introduction of many new airlines. This situation has led to an increase in aircraft movement frequency flying in and out of the airports and raised concerns about the effects of increased noise exposure levels on public health and the natural environment in the vicinity of the airports. Vietnam authority has also issued several documents to regulate the establishment of the noise contour maps to evaluate the current noise exposure levels around airports in Vietnam and recognized the noise problem in aviation as a significant issue. One of four measures to reduce the noise around airports introduced in the Balanced Approach to Noise Management of the International Civil Aviation Organization is noise abatement operational procedures. This research is one of the first attempts to provide a comprehensive study on predicting the noise levels and establishing noise contour maps around Tan Son Nhat International airport with the assumption that aircraft take-off following the noise abatement departure procedures 1 and 2 using MATLAB software. The computed noise contours for both procedures show that the day-evening-night equivalent noise levels range from 45 dB(A) to 60 dB(A) around the airport, with the difference in noise levels between the two procedures primarily occurring at the end of the runway due to the difference in stepped departures. These results provide a reference for the authorities to study further in applying suitable noise reduction plans in the vicinity of airports.

The round-the-clock vehicles operation at the airports, including in low visibility conditions with fog, snowfall, etc., requires the development of new methods for monitoring their traffic, including those that do not require direct visual contact between the dispatcher and the vehicles. In this study, a method for monitoring airport traffic based on acoustic scanning of the territory has been developed. The method allows you to control traffic remotely, including in conditions of ‘zero’ visibility. Controlled vehicles include ground vehicles that ensure airport operation, including tractors, tankers, buses for delivering passengers and the crew to the aircraft, snow plows, cars, etc. The method provides equipping the airport territory where vehicle traffic is possible with a network of acoustic sensors configured to detect noise generated by vehicle traffic, which allows you to receive traffic data on the airport territory. The structure of the airport traffic control system based on acoustic scanning and the algorithm of its operation is developed in the study for practical implementation of the method. To configure the acoustic sensors, which are the main element of the system, the noise generated by various types of airport vehicles was measured. The proposed method and the system implementing it can be used to prevent emergencies, as well as to ensure aviation security at airports.

Testo completoAbstract (sommario):
Aircraft noise exposure is a health risk and there is evidence that noise annoyance partly mediates the association between noise exposure and stress-related health risks. Thus, approaches to reduce annoyance may be beneficial for health. Annoyance is influenced by manifold non-acoustic factors and perceiving a fair and trustful relationship between the airport and its residents may be one of them. The distribution of aircraft noise exposure can be regarded as a fairness dilemma: while residents living near an airport may seem to have some advantages, the majority of residents living under certain flight routes or in their immediate proximity suffer from the disadvantages of the airport, especially the noise. Moreover, a dilemma exists between the airport’s beneficial economic impact for a region and the physical and psychological integrity of residents. Aircraft noise exposure through the lens of social justice research can help to improve our understanding of noise annoyance. Research indicates that the fairness perceptions of the parties involved can be enhanced by (a) improving individual cost–benefit ratios, (b) providing a fair procedure for deciding upon the noise distribution, and (c) implementing fair social interaction with residents. Based on the review of evidence from social justice research, we derive recommendations on how fairness aspects can be integrated into aircraft noise management with the purpose of improving the relationship between the airport and its residents, to reduce annoyance, and to enhance the acceptance of local aviation and the airport as a neighbor.

In recent years, concern over airport noise and its impact on surrounding communities has been spurred by the continual growth in air traffic together with urban development in close proximity to many airports around the world. This paper aims at studying the cases of Tallinn Airport and Tartu Airport, both in Estonia, with a focus on evaluating the airport noise and its impact on the neighbouring residential districts. Tallinn Airport is located within the city limits (only 4 kilometres from the city centre), and therefore the inhabited areas are also exposed to aviation noise. The main water catchment area for the city – Lake Ülemiste – and the nearest residential district are situated about 0.5 km from the airport. In 2003 stationary noise monitoring equipment was installed at Tallinn Airport to measure the noise level caused by starting and landing aircraft so that the necessary measures and sanctions can be taken. At Tartu Airport, the noise was recurrently measured in 2008, by using a TES 1352A sound level meter. The monitoring system at Tallinn Airport and the measurements at Tartu Airport enable operating noise and aircraft noise to be analyzed and predicted as a way to differentiate the landing fees for aircraft depending on noise and flight trajectory. According to the noise monitoring and measurements results, noise maps can be drawn.

The aviation sector is one of the fastest growing emitters of greenhouse gases worldwide. In addition, airports have important local environmental impacts, mainly in the form of noise pollution and deterioration in air quality. Although noise nuisance in the vicinity of airports is recognized as an important problem of the urban environment which is often addressed by regulation, other environmental problems associated with aviation are less widely acknowledged. In the climate debate, the importance of which is rising, aviation has remained under the radar for decades. In the present paper, we use the case of Brussels Airport (Belgium) to demonstrate that the local perception of air travel-related environmental problems may be heavily influenced by the communication strategy of the airport company in question. Basing our analysis on publicly available data, communication initiatives, media reports, and policy documents, we find that (1) the noise impact of aviation is recognized and mainly described in an institutionalized format, (2) the impact of aviation on local air quality is ignored, and (3) the communication on climate impact shows little correspondence or concern with the actual effects. These findings are relevant for other airports and sectors, since the type of environmental communication produced by airport companies can also be observed elsewhere.

There is a growing awareness of impact of aviation noise, such as health an annoyance issues. Community complaints that interfere with airport business has resulted in serious efforts to reduce aviation noise. However, even though improvements have been made, these efforts have not successfully reduced noise annoyance, in fact, community reactions towards airport operations have increased over time. The project INFRA, was initiated based on a community complaint regarding Arlanda airport, with the objective to develop knowledge of noise annoyance. Based on a broad interview study, a number of actors and their perspectives have been identified: neighbors, house and land owners, municipals, county board, land and environmental jurisdiction, transportation agency, transport administration, airports, air service providers, environmental protection agency and politicians. Results show that the aviation system contains opposing perceptions of noise and strategies which induce conflicts and breaches of trust from policies and regulations, all the way down to individual neighbors. An outcome is a set of identified dilemmas representing incompatible worldviews, and deep disagreement of values. After analysis these are concluded to represent conditions associated with what is called "wicked problem". The study results in an increased understanding and representation of the wicked aviation noise system.

As part of the agency's broader noise research program, the Federal Aviation Administration (FAA) has undertaken a multi-year research effort to quantify the impacts of aircraft noise exposure on communities around commercial service airports in the United States (U.S.). The overall goal of the study was to produce an updated and nationally representative civil aircraft dose-response curve; providing the relationship between annoyance and aircraft noise exposure around U.S. airport communities. To meet this goal, the FAA sponsored a research team to help design and conduct a national survey, known as the Neighborhood Environmental Survey (NES). A multi-stage and statistically rigorous process was used to select a representative sample of US airports, including a balanced sampling frame that included six factors: geographic distribution, temperature, day-night split, operational tempo, fleet mis, and population density. The research team computed Day-Night Average Sound Levels (DNL) for the 20 airports in two waves: first for survey respondent selection, and then for pairing with respondent locations to create the dose response curve. Analysis of the responses and the associated DNL was used to generate dose-response curves for each individual airport and a national dose-response curve showing the percent "Highly Annoyed" for a given noise level. The National dose-response curve created from the mail questionnaire shows considerably more people are highly annoyed by aircraft noise at a given noise exposure level compared to historical FICON data. This paper presents the airport selection and noise modeling process used to support the creation of the National dose-response curve. Additional information describing the motivation to conduct the NES and how its findings will help inform ongoing work to address aircraft noise concerns; and the survey methodology are provided in companion papers.

Airports are one of the segments within air transport and their serviceability ensures air transport efficiency. However, airports are among the largest contributors to the negative environmental impact of this kind of transport. Individual activities at airports leave a negative environmental footprint. By optimizing processes, it is possible to reduce the negative environmental impacts of these subjects. Airport winter maintenance is one of the important activities accompanying airports in geographical areas where winter season is expected due to the climate zone and weather conditions. Effective winter maintenance ensures optimal airport operation and has a significant impact on safety. However, the winter maintenance of the airport causes an excessive burden on the environment around the airports, in particular by applying de-icing agents to aircraft and movement areas, or by emissions and noise caused by equipment for snow and ice removal. The aim of the present article is to optimize the winter maintenance of the airport, namely the deployment of winter maintenance equipment with respect to meteorological conditions while maintaining the priorities for winter maintenance between individual airport areas. The aim of optimization is to achieve the saving of maintenance time and reduce the negative environmental impact of winter maintenance by effectively deploying equipment and devices.

Crackle is a sound quality that can be identified in the jet noise of tactical aircraft and may contribute to perceived community noise levels in the vicinity of military airports. Crackle has been linked to the skewness of the waveform pressure derivative, or derivative skewness. Recently, listener trials quantified the perceptual relationships between derivative skewness, loudness, and annoyance. We present a method to calculate a crackle-based adjustment to aircraft noise levels derived from annoyance. This crackle adjustment is applied to a large sample set of community noise measurements in the vicinity of departing military aircraft. Finally, we develop an empirical model to apply crackle-based adjustments to community noise models of tactical aircraft departures. The empirical model allows airport planners to examine how aircraft flight paths, altitudes, and engine conditions affect the crackle adjustment, which is significant in the airport's immediate vicinity and along the aircraft departure path.

This paper presents the research of noise level monitoring at the Zagreb Airport Ltd. The purpose of this paper is to show how the aircraft noise sources can be used as a tool for aircraft detection and for increasing flight safety. The noise measurement was made at the Zagreb Airport by using its professional noise monitoring system. The research has led to new findings, such as determining the aircraft model by measuring the noise level generated by an aircraft during final approach based on its frequency spectrum, as the connectivity from the airport’s side to the radar data was unavailable (only ATC). In addition, it is possible to determine the aircraft altitude and, perhaps most significantly, the increase of flight safety through the detection of potential failures on the aircraft structure and/or engine during the overflight of a noise monitoring terminal.

In 2013 and 2014, two main International Airports in Greece were evaluated through the European directive on noise environment 2002/49/EC: “Nikos Kazantzakis” International Airport of Heraklion Crete and “Ioannis—Kapodistrias” International Airport in Corfu, both located in highly touristic areas of Greece. Acoustic measurement’s campaign, environmental noise mapping simulations and population exposure to noise were implemented in order to produce a complete Strategic Noise Map. Correlated to this acoustic approach, a comprehensive interview campaign and a detailed soundscape analysis were also conducted in both airports’ adjacent areas (Alikarnassos district in Heraklion and the peninsula of Canoni in Corfu City) in order to understand the impact of aircraft movements on both local residents and tourists, and analyze the perception of the soundscapes. A similar evaluation was also executed in order to assess possible health effects by using the WHO’s DALY’s (Disability Adjusted Life Year) metrics for environmental noise in relation to the exposure of the population. This paper presents the main results of these representative case studies, attempting a combined assessment of both health effects and soundscape characteristics to be used as evaluation tools towards the management and the rehabilitation acoustic environment characterized mainly by aircraft noise in touristic areas.

Abstract The present work deals with the multiobjective, multidisciplinary optimisation of takeoff and approach operations of a commercial aircraft aimed at the mitigation of the impact of aviation noise on the population. The innovative approach used here couples the minimisation of the aircraft noise level at the certification points with the improvement of the sound quality. The latter objective represents the main novelty of the present work and is addressed using a spectral–matching approach to make the aircraft noise as close as possible to a target sound. The rationale underlying the research is the development of a community–oriented approach to the assessment airport operations in view of the complete redefinition of the future airport scenarios. Indeed, the air traffic growth, the rapid expansion of urban areas around airports, and the expected advent of urban air mobility, are transforming the aviation noise into a serious hazard to the sustainable development of society. The sound–quality–based objective imposes a comprehensive multidisciplinary approach also in the procedural optimisation, due to the detail required to estimate the noise spectrum composition. Two merit factors are minimised, specifically the EPNL at the noise certification points and the Lp –norm of the difference between the noise produced by the configuration under analysis and a target sound. The target sounds are obtained by using sound engineering techniques aimed at the sound quality improvement, on the basis of the results of the psychometric tests campaigns performed within the projects SEFA and COSMA. The minimisation is achieved adopting a global evolution method, and the results are presented in terms of approximated Pareto frontiers for a single–aisle aircraft in both takeoff and landing conditions.

This paper evaluates the Technical Efficiencies (TEs) of a group of airports in East China by applying a three-stage Data Envelopment Analysis (DEA) method. The merit of this method allows us to consider the impact of the environmental factors on measuring airport efficiencies. Three variables, i.e. per capita Gross Domestic Product (GDP), the proportion of the tertiary industry, and the number of tourists, are used to represent the environmental factors. The results show that the environmental factors have airport-specific impacts on the value of the efficiencies. Additionally, airport TE are dominated by both Pure Technical Efficiency (PTE) and Scale Efficiency (SE). Based on empirical results, airport specific strategies can be provided to enhance airport efficiency, such as taking the effects of environmental variables and the statistical noise into consideration when analysing the airport efficiency, improving airport efficiencies according to their own conditions and improving the PTE or SE according to their categorizations.

Testo completoAbstract (sommario):
Noise is considered as one of the main environmental impact of Adi Soemarmo International Airport (ASIA), the second largest airport in Central Java Province, Indonesia. In order to manage the noise of airport, airport noise mapping is necessary. However, a model that requires simple input but still reliable was not available in ASIA. Therefore, the objective of this study are to develop model using Matlab software, to verify its reliability by measuring actual noise exposure, and to analyze the area of noise levels‥ The model was developed based on interpolation or extrapolation of identified Noise-Power-Distance (NPD) data. In accordance with Indonesian Government Ordinance No.40/2012, the noise metric used is WECPNL (Weighted Equivalent Continuous Perceived Noise Level). Based on this model simulation, there are residence area in the region of noise level II (1.912 km2) and III (1.16 km2) and 18 school buildings in the area of noise levels I, II, and III. These land-uses are actually prohibited unless noise insulation is equipped. The model using Matlab in the case of Adi Soemarmo International Airport is valid based on comparison of the field measurement (6 sampling points). However, it is important to validate the model again once the case study (the airport) is changed.

Testo completoAbstract (sommario):
The purpose of this study is to evaluate the noise generated by aeronautical operations around Juan Santamaría Airport and its compatibility with the land use and the proposed zoning around the airport. Aircraft noise can produce discomfort, interference with daily activities, and excessive vibrations; hence, land use planning around airports is of importance.
Maps were prepared through computational models representing the noise levels generated by the operations of the airport. The operations were analyzed by aircraft type, schedules, and flight tracks, for 2013 and projections for: 2016, 2026, and 2036. Noise level data were collected with a sound level meter at 28 points surrounding the airport.
Comparing the annual maps of 2013 and 2036 it was determined that 41,24 % of the analyzed area will present clearly perceivable increases (5 dB(A) to 10 dB(A)), and 1,36 % of the area will have double loudness increases (10 dB(A) to 14 dB(A)).
The 2016 maps show locations where it is recommended to incorporate solutions in the construction regulation that reduce between 25 dB and 30 dB in the residential and scholar areas located within 65 dB(A) and 70 dB(A), such as Coco, Rincón Monge, Rincón Herrera, and Bajo Sorda. This finding is supported by field measurements.
The proposed zoning was contrasted against the yearly day-night average sound level of 2036. The biggest issue of excessive aircraft noise is located near the west runway where a range above the 75 dB(A) is expected. Any edification of permanent residence must be banned in here.

Safety and Security in Airports flight something that should not be ignored. To anticipate a situation that allows the occurrence of accident and incident, the airport operator and all units of the organization that is the environment of the airport should be able to identify hazards I problems based on events that never happened. The survey was conducted in Supadio Airport towards the application of hazard identification and safety risk management, using the method of comparative analysis and evaluation to make mengukuran of 13 variables. Based on measurements of 13 variables, obtained by 3 variables included in the criteria can not be accepted on condition that there is, namely a foreign object variable that has the potential to cause damage to the aircraft (foreign object damage 4.B), the variable things that can disrupt flights (obstacle 4.B), and variable in Apron vehicles (vehicle in Apron 5.C). Two criterion variables risk control/ mitigation requires a management decision that is, variable Noise (noise 5), and variable Security Issues (security issues. 2A). This value indicates that the 3 variables are included that are essential for risk reduction targets.Keywords: Airports, Safety Management System, hazard identification, safety risk

In order to solve the problems of multifactor and fuzziness of airport noise environmental impact, the multilevel fuzzy cluster analysis for comprehensive assessment of airport noise environmental impact was proposed in this paper. The method is a quantitative analysis of the environmental impact of airport noise, which integrates Fuzzy Cluster Analysis with Analytic Hierarchy Process (AHP). The results show that the method is better reflecting of fuzziness between the levels of noise environmental pollution, better solving the problem of weight factors of various indicators, and making assessment results more reasonable. This work can provide decision support for airport noise manager.

Testo completoAbstract (sommario):
Many airports all over the world have established restrictions for the use of thrust reverse for slowing down aircraft after landings, especially during the night period, as a way of reducing noise impact and the number of complaints in the vicinity of airports. This is the case of Madrid airport, where the Universidad Politécnica de Madrid, in collaboration with AENA, and the Politecnico di Milano have been researching, and developing intelligent instruments to improve the detection and classification of thrust reverse noise among other noise sources present in the airport. Based on a traditional approach, the thrust reverse noise detection tool detects two consecutive sound events, and applies pattern recognition techniques for the classification of each of them (such as landing and thrust reverse). A second improvement refers to the use of a microphone array linked to a noise- monitoring unit, which enables tracking the direction of arrival of the sound, thus improving the classification rates. By taking the latter, it is also possible to track the aircraft location along the runway, which enables sound pressure measurements to be transformed into sound power level estimations. Although the novel instrument can still be optimized and customized, the results have shown quite good classification rates (over 90%).
