Full textAbstract:
Aquatic anthropogenic noise is on the rise, with growing concern about its impact on species that are sensitive to low-frequency sounds (e.g. most fish and invertebrates). We investigated whether the reef fish Halichoeres bivittatus living in both noisy and quiet areas had differing levels of baseline stress (measured as whole-body cortisol) and whether they would exhibit a physiological stress response when exposed to boat noise playbacks. While the playback experiments significantly increased cortisol levels in fish from our experiment compared to baseline levels, there were minimal pairwise differences across treatments and no difference in baseline stress for fish living in noisy vs. quiet areas. These results may be explained by low overall auditory sensitivity, habituation to a fairly noisy environment (due to biological sounds), or that boat noise simply may not represent an immediate threat to survival in this species. These findings contrast recent studies that have shown elevated stress responses in fishes when exposed to boat noise and highlights that inter-specific differences must be considered when evaluating potential impacts of anthropogenic noise on marine life.

COVID-19 had an impact on the daily life, human activities, various sectors, and the environment. Accordingly, the aim of this research was to examine the effect of the COVID-19 pandemic lockdown (COVID-19 PL) on the environmental parameters. The studied environmental parameters were solid waste, noise, air, water, wastewater (WW), soil and green areas, natural environment and resources, light pollution, radiation pollution, energy and others. The main environmental issues were divided into seventy sub-parameters. Results revealed that COVID-19 PL increased a number of parameters, such as domestic and hospital wastes, noise at home, aquatic life and water quality, domestic WW amount, green areas, animal and birds movement, natural energy, rodents etc.; while, it decreased several factors for instance commercial/industrial solid waste, traffic and outdoor noises, air pollution and particles, water contamination, WW production, cutting trees and hunting, fuel extraction and mining, artificial light and radiation, fuel combustion, tourist etc. Alternatively, some parameters, such as black water, natural radiation, and normal lighting remained as before COVID-19 PL. Positive, nil, and negative impacts of the parameters on the environment due to COVID-19 PL were 81.43 %, 5.71 %, and 12.86 %, respectively. Positive impacts of the COVID-19 PL on the environment were greater than negative influences and lockdown was regarded as a respiration of the natural environment. Currently, prediction of seasonal impact on spreading COVID-19 is difficult.

Full textAbstract:
Increasing attention is being paid to the ecological consequences of underwater noise generated by human activities such as shipping and maritime industries including, but not limited to, oil and gas exploration and extraction, sonar systems, dredging and the construction of offshore renewable energy devices. There is particular concern over the extension of these activities into previously undeveloped areas of the oceans, including Polar Regions and areas of coral reef habitat. Most of the concern by regulators and others has focussed upon effects upon marine mammals and other protected species. However, examining the impacts upon the overall ecology of affected habitats is also important as it may be dominated by effects upon the far larger biomasses of fishes and invertebrates, which do not have the same degree of legal protection. Many of these assessments of the impact of noise on fishes and invertebrates have overlooked important issues, including the sensitivity of a substantial proportion of these species to particle motion rather than sound pressure. Attempts have been made to establish sound exposure criteria setting regulatory limits to the levels of noise in terms of effects upon mortality levels, injury to tissues, hearing abilities, behaviour, and physiology. However, such criteria have almost exclusively been developed for marine mammals. Criteria for fishes and invertebrates have often had to be assumed, or they have been derived from poorly designed and controlled studies. Moreover, the metrics employed to describe sounds from different sources have often been inappropriate, especially for fishes, and invertebrates, as they have been based on sound pressure rather than particle motion. In addition, the sound propagation models employed to assess the distances over which effects might occur have seldom been validated by actual measurements and are especially poor at dealing with transmission under shallow water conditions, close to or within the seabed, or at the surface. Finally, impacts on fish and invertebrate populations are often unknown and remain unassessed. This paper considers the problems of assessing the impact of noise upon fishes and invertebrates and the assessment procedures that need to be implemented to protect these animals and the marine ecosystems of which they form an integral part. The paper also suggests directions for future research and planning that, if implemented, will provide for a far better scientific and regulatory basis for dealing with effects of noise on aquatic life.

Robertina Šebjanič, a Ljubljana artist, describes in this text her research-based artworks dealing with cultural, (bio)political and ecological realities of human imprint on aquatic environments and its consequences and challenges. Based on Paul Celan’s quotation: ‘there are still songs to sing beyond mankind’, the author propose in this article to explore an odyssey of interspecies communication, a way of discovering parameters to restore a deep relationship within all of life and a key to better understanding of the earth’s environment. The Aurelia 1+Hz project is divided in two parts: the performance Aurelia 1+Hz / proto viva sonification looks into a new critical redefinition of social values and new attitude towards cohabitation of interspecies, while the installation Aurelia 1+Hz / proto viva generator deals with the biopolicy of prolonging life. In the project Aquatocene, the artist investigates the phenomenon of underwater noise pollution created by humankind in the seas and oceans. It encourages rethinking the human impact on the (under)water habitats.

Full textAbstract:
Ground vibrations induced by large flood discharge from a dam can damage surrounding buildings and impact the quality of life of local residents. If ground vibrations could be predicted during flood discharge, the ground vibration intensity could be mitigated by controlling or tuning the discharge conditions by, for example, changing the flow rate, changing the opening method of the orifice, and changing the upstream or downstream water level, thereby effectively preventing damage. This study proposes a prediction method with a modified frequency response function (FRF) and applies it to the in situ measured data of Xiangjiaba Dam. A multiple averaged power spectrum FRF (MP-FRF) is derived by analyzing four major factors when the FRF is used: noise, system nonlinearity, spectral leakages, and signal latency. The effects of the two types of vibration source as input are quantified. The impact of noise on the predicted amplitude is corrected based on the characteristics of the measured signal. The proposed method involves four steps: signal denoising, MP-FRF estimation, vibration prediction, and noise correction. The results show that when the vibration source and ground vibrations are broadband signals and two or more bands with relative high energies, the frequency distribution of ground vibration can be predicted with MP-FRF by filtering both the input and output. The amplitude prediction loss caused by filtering can be corrected by adding a constructed white noise signal to the prediction result. Compared with using the signal at multiple vibration sources after superimposed as input, using the main source as input improves the accuracy of the predicted frequency distribution. The proposed method can predict the dominant frequency and the frequency bands with relative high energies of the ground vibration downstream of Xiangjiaba Dam. The predicted amplitude error is 9.26%.

Full textAbstract:
The effect of covid 19 on human health was devastating and the fatality rate was high around the world. World Health Organization declared the outburst of this infectious disease a pandemic situation. To check the rapid dispersal of the COVID-19 virus, most countries of the world enforced quarantine and strict lockdown. The effects of COVID-19 lockdown on environmental health draw the attention of the scientific communities. Therefore, this research paper inspected and narratively reviewed the observed effects of COVID-19 lockdown on the changes in the environmental quality based on secondary research data. The work provides a distinct indication considering the impacts executed by COVID-19 lockdown on the air, water, soil, and noise as typical environment elements. It has been widely reported that the amount of pollution in the air, water, soil, and noise exhibited a significant decline during lockdown period. It has been noticed in different literature that global air quality improved because of less anthropogenic emissions of air contaminants and atmospheric particles. For instance, releases of carbon, nitrogen, sulfur and particulate matter are reduced and ozone layers were reported to being increased. Aquatic life and water ecosystem have also been restored in many countries due to less commercial fishing. Moreover, soil pollution was less due to a significant decrease in solid and water waste dumping. Because of less transportation of vehicles, industrial and other urban activities, sound pollution dropped to a significant level. Clean beaches, transparent seawater, wildlife sightings and free movement of animals and birds were also found in some counties during lockdown. However, these effects of lockdown were temporary, as the world again enters the pre-lockdown situation. Human attitudes must be changed to continue the positive impact on the environment. World policymakers should take the necessary steps to guarantee the steadiness of the positive environmental effects derived from the COVID-19 lockdown.

Full textAbstract:
The outbreak of the novel coronavirus infection, COVID-19 was initiated from the seafood market in Wuhan city of China in December 2019 and within a couple of months it turned out to be a pandemic and global health emergency. Due to increased human activity, transportation, industrialization and urbanization create a detrimental effect on the global environment in terms of air pollution, water pollution, noise pollution, soil pollution, climate change, ozone layer depletion and change of biodiversity and ecosystem. The reduction of air pollution was strongly associated with travel restrictions and industrial shutdown during this pandemic so that on average, the air quality index (AQI) and five air pollutants (PM2.5, PM10, NO2, aerosol and carbon emissions) have decreased. During the ongoing lockdown, nature has started to revive itself. Rare birds and animals have starting to come out of hiding. People residing near Yamuna River in Delhi, India say that the water is cleaner due to the lockdown. The dip in air pollution is leading to clearer skies and migratory birds can fly freely without human interference or threat. It all seems like nature is taking a breath of fresh air with the lack of human activity. The present study discusses the indirect impact of covid-19 pandemic on environment and nature. It also describes the behavioral changes of arial, aquatic and terrestrial life during the lockdown period.

Full textAbstract:
The advantages of low-impact development approaches, such as green walls in an urban environment, are numerous. These systems can be applied for managing stormwater, saving energy consumption, decreasing noise pollution, improving runoff quality, improving life quality, and so forth. Besides, atmospheric water harvesting methods are considered a nonconventional water source. There are many studies about the analysis and advantages of green walls and atmospheric water harvesting conducted separately. However, the use of a combined system that uses fog harvesting in the irrigation of green walls has received less attention in previous studies, and therefore in this research, the feasibility of a novel green wall platform was investigated. At first, the potential of using green walls and atmospheric water harvesting in different climates was analyzed. Then a new combined system was proposed and explained. The study results determined that atmospheric water harvesting can be applied as a source of irrigation for green facilities, particularly in the dry season and in periods with lower precipitation. In the Mediterranean climate, summer fog harvesting yields 1.4–4.6 L/m2/day, and the water consumption of green walls is about 4–8 L/day/m2. This can improve one issue of green walls in an urban environment, which is irrigation in summer. Furthermore, the novel system would protect plants from severe conditions, improve buildings’ thermal behavior by decreasing direct sunlight, and increase conventional green walls’ efficiency and advantages.

Full textAbstract:
Being able to study anatomical structures of wildlife species for science and clinical practice is of great importance. We aimed to describe the normal gross osteology of the common adult capybara Hydrochoerus hydrochaeris (Linnaeus, 1766), using macerated bone specimens and high-resolution digital radiography. The complete axial and appendicular skeleton was further compared with previously reported anatomical findings. For this purpose, we used three adult capybara cadavers (two females and one male), with a mean bodyweight of ±50 kg. Some H. hydrochaeris-specific morphological characteristics, especially in the skull region, show evidence of adaptation to aquatic life, such as an elongated head shape, with eyes, ears, and nose, located dorsally, to stay above water. Additionally, the entire bone structure demonstrates the size and weight support of the largest rodent and its adaptation with respect to foraging and locomotion behaviors. As a semi-aquatic herbivore, classified as cursorial (having limbs adapted for running), the authors believe it should be reclassified as cursorial-swimming/diving. Moreover, we argue to consider a differentiation between H. hydrochaeris silvestris to H. hydrochaeris synanthrope, due to substantial weight variation, in some cases > 100%. This inevitably has an impact on the development of bone structure, thus influencing habitual adaptation, and consequently, its clinical implications and animal handling. Radiography exams helped in the identification of bone structures, which otherwise were not observed in anatomical specimens, such as ossa sesamoidea, including the ossicle lunulae. Likewise, the radiographs were particularly helpful in overall better comprehension of the intubation and catheterization procedures. We believe this work can contribute as a reference to anatomical studies for students and professionals acting in clinic, surgery, and research.

Full textAbstract:
Water is essential for the survival of plants, animals, and human beings. It is imperative to effectively manage and protect aquatic resources to sustain life on Earth. Small tributaries are an important water resource originating in mountain areas, they play an important role in river network evolution and water transmission and distribution. Snow and cloud cover cast shadows leading to misclassification in optical remote sensing images, especially in high-mountain regions. In this study, we effectively extract small and open-surface river information in the Upper Yellow River by fusing Sentinel-2 with 10 m resolution optical imagery corresponding to average discharge of the summer flood season and the 90 m digital elevation model (DEM) data. To effectively minimize the impact of the underlying surface, the study area was divided into five sub-regions according to underlying surface, terrain, and altitude features. We minimize the effects of cloud, snow, and shadow cover on the extracted river surface via a modified normalized difference water index (MNDWI), revised normalized difference water index (RNDWI), automated water extraction index (AWEI), and Otsu threshold method. Water index calculations and water element extractions are operated on the Google Earth Engine (GEE) platform. The river network vectors derived from the DEM data are used as constraints to minimize background noise in the extraction results. The accuracy of extracted river widths is assessed using different statistical indicators such as the R-square (R2) value, root mean square error (RMSE), mean bias error (MBE). The results show the integrity of the extracted small river surface by the RNDWI index is optimal. Overall, the statistical evaluation indicates the accuracy of the extracted river widths is satisfactory. The effective river width that can be accurately extracted based on satellite images is three times the image resolution. Sentinel-2 MSI images with a spatial resolution of 10 m are used to find that the rivers over 30 m wide can be connectedly, accurately extracted with the proposed method. Results of this work can enrich the river width database in the northeast Tibetan Plateau and its boundary region. The river width information may provide a foundation for studying the spatiotemporal changes in channel geometry of river systems in high-mountain regions. They can also supplement the necessary characteristic river widths information for the river network in unmanned mountain areas, which is of great significance for the accurate simulation of the runoff process in the hydrological model.

Abstract The paper reports the main contents of the guidelines developed in the framework of the project ANCHOR, acronym of Advanced Noise Control strategies in HarbOuR, which is a European Project funded as part of the announcement Life 2017. The guidelines represent an updated version of those elaborated in the NoMEPorts project named ‘Good Practice Guide on Port Area Noise Mapping and Management’; the aim is to define a common approach in port noise monitoring and assessment, considering the outcomes of previous EU funded projects and the algorithms defined by the European Directive 2015/996, in order to produce Port Noise Impact Assessments to be included in ports Environmental Management Systems (EMS). The procedures described in the guidelines will guide professionals in organizing and managing geographical data, in characterizing noise sources and defining, for each of them, the correct noise emission power level, in evaluating noise propagation and people exposure to noise and, finally, in selecting the most efficient mitigation action by means of a cost benefit analysis. Moreover, the paper reports the results of a comparison between noise mapping outcomes obtained using the new noise mapping algorithms defined by the 2015/996 Directive and the old 2002/49/EC Annex II ones; especially at long distances from the source the differences between the two methodologies are not negligible.

Possibilities to use unmanned aerial vehicles (UAVs) are rapidly growing. With the development of battery technologies, communication, navigation, surveillance, and autonomous systems in general, many UAVs are expected to operate at relatively low altitudes. Thus, the problem of UAV noise impact on human health and well-being will be more pronounced. In this paper, we conducted noise measurements of two UAVs of different performance (quadrotor and hexarotor) in flying up and down, hovering, and overflight procedures. Respondents of good hearing who were confirmed by audiogram measurement and had participated in the survey during UAV noise measurement gave their subjective assessments on the UAV noise perception. UAV noise measurements and subjective respondents’ assessments were analysed and related. UAV noise analysis showed that the parameters measured at the same measurement point for the hexarotor were higher than those for the quadrotor in flying up and down and flying-over procedures. Low frequency noise was present in the noise spectrum of both drones. Participants were able to distinguish between the noise of UAVs and had a generally more negative experience with the hexarotor. Regardless of the noise perception, more than 80% of the respondents believe there are more pros than cons for UAV introduction into everyday life.

Full textAbstract:
Within New Zealand and eastern Australia, over 58,000 southern right whales were harvested by commercial whalers between 1790 and 1980, with approximately 19,000 harvested from south-eastern Australia. Local extirpation is believed to have led to a loss of cultural memory of calving areas, contributing to the limited recovery of the south-eastern Australian population. While the number of whales observed using the south-eastern Australian coastline is increasing, there has been no change over three decades in the annual abundance of cow-calf pairs at Logans Beach in Warrnambool, Victoria, the only established calving ground in the region. Knowledge of life history parameters of the south-eastern Australian population is lacking. Here, we examine sightings and photo-identification data from southern Australia to investigate calving intervals, long range movements and fidelity to the Logans Beach nursery ground. Sightings data revealed at least 93 calves were born at Logans Beach between 1980 and 2018 (an average of 2.6 per year) with a mean calving interval of 3.5 ± 1.0 years (± SE, n = 34). Comparison between photo-identification catalogues compiled for south-eastern and south-western Australian populations shows that southern right whales are wide ranging within southern Australian waters. Females can be sighted at locations as far apart as 3,800 km across seasons and there is overlap in the wintering range of the south-eastern and south-western populations, with at least 7% of whales using both regions. We also provide the first report of an Australian southern right whale female with strong site fidelity to a calving area in one region relocating long-term to a calving area in another region. This work highlights several knowledge gaps, such as; the location of feeding and conception grounds for this population as well as the degree of mixing between the two Australian populations outside their wintering areas. In addition, the proportion of female calves born at Logans Beach returning to their natal site to calve remains unclear. Our work provides the first assessment of calving rates, movement and site fidelity within the south-eastern Australian population, critical for understanding constraints to recovery and informing conservation management of southern right whales in Australia. Targeted, long-term monitoring programs across the south-eastern Australian region are needed to provide demographic information on which to base predictions of the impacts of anthropogenic threats such as noise disturbance, entanglement and vessel strike.

Because of climate change and environmentally friendly energy policy in Korea, the demand for a new renewable energy development has been increased. Especially, the onshore and offshore wind turbines have played an important role in the power system for generating eco friendly energy. However, in the stage of constructing and operating the onshore and offshore wind turbines, the aerodynamic and underwater noise effect on human and marine life becomes a prominent figure on a social issue, and it is necessary to prepare the assessment method of these noise impacts in order to prevent the influences on human and marine life in advance. Therefore, this paper is focused on suggesting the evaluation plans of the noise effect from the onshore and offshore wind turbines.

Full textAbstract:
Environmental noise and vibration induced by building construction are increasingly prominent in daily life. If the noise and vibration level exceeds the corresponding standard limits stipulated by the country, humans’ normal life, working, or studying efficiency would be interfered. This paper aims to explore how residents respond to noise and vibration mainly induced by the building construction. The noise and vibration measurements, as well as a questionnaire survey, were conducted. Through analysis and comparisons, it is shown that the noise impacts were concentrated in the area near the construction site. For the noise and vibration transmission within the building, the noise levels were amplified in the lower floors and gradually attenuated with floors, and the vibration levels decayed with the floors. The noise impact was much greater than the vibration impact. Building construction was found to be one of the most annoying noise and vibration sources, while the subway operation has little impact on residents according to either subjective or objective evaluation. The ratio of noise and vibration dissatisfaction was less than that of annoyance, which demonstrated that the residents’ psychological capacity was high toward the impact of noise and vibration. The proposed dose-response relationship can apply in a similar community environment. Once the noise levels within the building obtained, the residents’ noise annoyance can then be estimated.

Science, Technology, Engineering, Mathematics in education is commonly referred to as STEM. The last decades illustrate that our society is transferring into an ever accelerating technological environment. In parallel, the general public became an important driving force in collecting citizen science data to trigger legislative pressure and impact on policy makers to accelerate the improvement of their quality of life. That practice is currently extending into the environmental impact of noise related quality of life. This publication suggests to merge those educational STEM goals, citizen science monitoring and the need for population based noise monitoring data for efficient policy support. The presented educational project can be regarded as a proof-of-concept and can be repeated in different schools and classes every year. This approach has the potential to acquire abundant noise monitoring data and provides an unbiased population sampling dataset by design. This population driven involvement allows to assess real-life and long-term noise policy impact and could become a fundamental pillar in achieving the overall societal goal of improving noise related environmental quality of life.

Background: The purpose of this study was to describe the relationship between noise exposure, selected health conditions, and well-being among nurses. Methods: A secondary analysis was performed on data obtained from 3,818 U.S. nurses who responded to a survey regarding noise exposure, health conditions, stress, professional quality of life, and workplace support. Findings: Those who reported high noise exposure reported more health conditions, higher stress and burnout scores, and lower supportive environments. High noise exposure was significantly associated with lower professional quality of life. Conclusion/Application to Practice: Noise may impact the health and quality of professional life of nurses. Occupational health nurses should advocate for the regular monitoring of nurses’ exposure to hazardous noise at work, compare it to OSHA permissible levels, and collaborate with the occupational health team to ensure safe noise levels are maintained. Occupational health nurses should advocate for expanded research on effects of noise on health.

The growth of the urban population and its activity in major cities has led to various public health challenges, including environmental pollution, which are reflected in a decrease in the well-being of societies. This paper presents a predictive tool used to mitigate the noise impact study of commercial centre noise on the surrounding houses, the study being conducted prior to its construction. Before the construction of the supermarket, the sound pressure levels from the façade of the surrounding building are measured to have a background noise level of the analysed area. The noise impact study is made using prediction software in which the houses and the shopping centre buildings are numerically modelled. The main noise sources of the commercial centre, defined in numerical predictions, are represented by the air conditioners, heat pumps situated on the roof and the noise generated by the activities from the supply ramp. The noise impact evaluation is performed at different heights and by determining the number of affected inhabitants. To reduce the number of exposed inhabitants to noise, four technical solutions are presented. The proposed noise solutions are based on technical and economic analyses and also on the urban landscape. The study presents the noise prediction for which the propagation calculus was made according to ISO 9613-2. The noise limits were evaluated according to the Romanian national legislation. The final part of this study presents the noise measurements performed after the construction of this shopping centre and the validation of the implemented noise reduction solution.

As with any asset on the highways network, it is common sense to allow for realistic maintenance costs when choosing and procuring a noise barrier system. A short-term approach of focussing on newly installed prices alone creates a false economy and potentially stores up financial hardship for the future. The adverse impact of road traffic noise on public health is also long appreciated. Being able to quantify in financial terms not the only perceived annoyance but also the long-term damage to health due to traffic noise helps to justify why one particular noise barrier design will benefit the community more than another over its life-cycle.

ABSTRACT Purpose: to analyze the perception and knowledge of dentists on occupational noise, its prevention, and effects on their health and quality of life. Methods: a cross-sectional study carried out with 54 dentists of both genders. Two questionnaires were applied: one addressing issues of perception and knowledge on noise and its effects, and another on Quality of Life (SF 36). Results: the workplace noise was considered within medium intensity, and a health risk. Some professionals (59.2%) reported knowing noise prevention methods, although they do not use them. Complaints and the most frequently reported symptoms were irritability, difficulty in understanding speech and tinnitus. The perception of the Quality of Life was worse among men. There was association between pain and perception of noise intensity. Conclusion: noise was considered, regardless of gender, harmful to health and associated with perception of musculoskeletal pain. Symptoms and complaints caused by noise have been reported to negatively impact the professional activity of dentists, however, most of them do not adopt preventive measures.

Introduction: The studies on the consequences of noise to the auditory system are well documented, particularly in workers’ health. Nevertheless, few studies in the field yet have related postural control to occupational noise exposure. Objective: To investigate the association between the history of occupational noise and the postural control in older adults. Materials and Methods: Cross-sectional study that included individuals of both sexes older than 60 years. All of them had their postural control assessed on a force platform. The occupational noise was assessed with an audiological anamnesis questionnaire. The hearing loss was assessed using the pure-tone threshold audiometry. The Tinnitus Handicap Inventory questionnaire was used to quantify the impact of tinnitus on daily life of the older adults. Results: 90 older adults (87.8% women, 70[64-75] years old) were analyzed. The history of occupational noise exposure was associated with a worse postural control in older adults, regardless of the person’s age (ANCOVA; P < 0.05). Moreover, the greater the hearing loss, the greater the body instability of the older adults (r≤0.36 for all). Finally, postural control was related to tinnitus presenting correlations with catastrophic Tinnitus Handicap Inventory (r = 0.314; P = 0.038) and functional Tinnitus Handicap Inventory (r = 0.430; P = 0.010). Conclusion: Postural control of older adults is related to the history of occupational noise exposure, hearing loss and tinnitus impact on older adult’s daily life.

Quality of work life and its link to quality of life by noise-exposed workers Objective: It was aimed to evaluate both the quality of work-life and quality of life of factory workers working in noisy environments by using the quality of work-life scale and the WHOQOL-BREF (TR) scale and to examine the correlation of the two scales. The secondary aim of our study is to draw attention to the negative impact of noise-induced hearing loss on quality of life and the necessity of measures to protect individual workers. Material and Method: Forty participants aged between 18-45 with and without noise-induced hearing loss (20 participants) were included in the study. Pure tone audiometry tests were performed on the participants. Then, they were asked to answer the WHOQOL-BREF (TR) and Quality of Work Life Scale items. Results: A statistically significant difference was found between the years of work, quality of life, and quality of work-life scores between participants with and without hearing loss. Moderate to strong correlations were observed between the scales assessing the quality of life and work-life. Conclusion: Occupational noise is an important risk factor for hearing loss in workers. Considering that the quality of life of workers exposed to noise is adversely affected, it is necessary to determine the noise exposure, evaluate the negative psychological effects of noise and reduce exposure to noise if necessary. Keywords: Occupational noise, noise exposure, industrial noise, hearing loss, quality of life, quality of work-life

Full textAbstract:
Underwater noise from shipping and its impact on marine life has been addressed by numerous governments and non-governmental organizations since the early part of the twenty-first century. The issue has reached the highest level of shipping regulation, the International Marine Organization or IMO, a sub-organization to the United Nations. Since the 1990's, marine biologists have known that the increase in underwater-radiated noise has multiple negative impacts on various species of marine life and each species has different impacts with different acoustic thresholds. At regulatory levels, it is believed that the problem can be solved by reducing underwater radiated noise from all vessels; shipping noise. However, there is no simple solution. It requires a cross-functional team including marine-biologists, underwater acousticians, vessel owners/operators, and naval architects/ship designers. Solutions will only occur with efforts directed at the highest governmental and inter-governmental levels. Topics that are being addressed include impacts on marine life, underwater noise limits, operational restrictions on shipping, shipboard noise mitigation, and methods of underwater sound prediction and measurement.

Background: Dementia and cognitive impairment were significantly associated with hearing loss. The impact of hearing loss on dementia and cognitive impairment is understudied, particularly for different effect on cognitive impairment according to types of hearing loss. Objective: The present study was conducted to elucidate the association between clinically diagnosed dementia and hearing loss with consideration of the type of hearing loss among an elderly population, and to explore the effects of different types of hearing loss on preclinical cognitive impairment. Methods: Data (n = 59,675) from the Korean National Health Insurance Service–Health Screening were used to calculate odds ratios (OR) for cognitive impairment according to type of hearing loss (conductive, sensorineural, mixed, and noise-induced hearing losses, and presbycusis). Cognitive impairment was assessed using the Korean Dementia Screening Questionnaire-Prescreening (KDSQ-P). Results: Cognitive impairment was significantly associated with conductive (OR: 1.45, 95% confidence interval (CI): 1.20–1.77), sensorineural (OR: 1.23, CI: 1.12–1.36), and noise-induced hearing loss (OR: 1.32, CI: 1.12–1.56), and presbycusis (OR: 1.53, CI: 1.25–1.87). Among participants scoring positive on the KDSQ-P (score≥4), the KDSQ-P score was significantly elevated in the mixed and noise-induced hearing loss groups. Conclusion: This study revealed a significant correlation between different types of hearing loss and cognitive impairment. Noise-induced hearing loss is especially important because it occurs earlier than other types of hearing loss and has large effects on cognitive impairment.

Full textAbstract:
As part of a collective research effort towards greener aviation, the present study focuses on the noise impact of aircraft operations around major airports. To this end, an aircraft noise prediction platform is developed, which relies on state-of-the-art functionalities as well as more specific, innovative features. Originally built upon the Aircraft Noise and Performance (ANP) database and its Noise–Power–Distance (NPD) table, the method is further refined to alleviate most of their inherent limitations (e.g., standardized and simplified aircraft noise scenarios). The resulting aircraft noise prediction platform is validated against benchmark cases of increasing complexity, being then applied to real-life situations involving actual aircraft operations around Hong Kong International Airport (HKIA). Specific comparative analyses are conducted, which allow highlighting the variability of the noise impact by aircraft, depending on their type (A330, B777) and/or operational conditions (power settings, meteorological conditions, routes, banks, etc.). The study delivers insightful outcomes, whether phenomenological (aircraft noise impact) or methodological (aircraft noise prediction). As a by-product, it illustrates how noise prediction methods/platforms such as the present one may help in guiding the further expansion of airport operations and/or infrastructures (as is currently the case with HKIA).

With a growing interest in the study of urban life and health, evidence indicates that the quality of the environment in which we live can have implications for our subjective well-being and health. This study assesses the potential impacts of perceptions of visual air pollution, olfactory air pollution, and noise pollution on self-perceived health, self-perceived happiness, and satisfaction with life, through the calculation of ordinal logistic regressions, using the information of an online survey carried out in Quito, Ecuador. We found that perceptions of unpleasant odors and noise pollution influence self-perceived health, self-perceived happiness, and satisfaction with life. The obtained results may support the incorporation of citizens’ perspectives to better understand environmental pollution and to enrich local planning for urban sustainability.

In this study, the environmental impacts of the production and field application of synthetic resin formwork were quantitatively compared to the Euro form. The noise test results showed an average of 107.3 dB (A) for the Euro form and 99.7 dB (A) for the synthetic resin formwork. Additionally, when the number of uses was considered, the CO2 emissions from the synthetic resin formwork were approximately 32% lower than the Euro form. Based on these results, it is expected that the use of synthetic resin formwork will reduce material production by half and reduce CO2 emissions compared to channel formwork.

Noise and visual pollution are major arising pollution in the world. These types of pollution cause negative impacts on the inhabitants of the inbuilt environment or on the outside communities. Visual pollution affects the overall wellbeing of the community and retards quality of life. Moreover, noise pollution arises mainly from transportation, construction, industrialization and electronic equipment or tools. This study was carried out to mitigate the noise and visual pollution by proposing basic design strategies that can be applicable anywhere. Proper town and building planning could be a better option with noise tolerant buildings and noise barriers. In addition, building designs and selection of suitable construction materials also have to be considered in mitigating noise and visual pollution. However, it is mainly the responsibility of the decision makers of the society to make the development look and feel better as well as of the designers and planners to implement proper methods to ensure that the community fits the regulations.

ABSTRACT Introduction Workers with excessive noise exposure can develop problems related to general health, hearing and have changes in quality of life, with Noise-Induced Hearing Loss (NIHL) being the most common change associated with hearing. Dentists, when using different types of equipment for clinical and surgical procedures, end up being exposed to noise daily. Hearing loss is associated with decreased life quality, including an increased risk of loneliness, isolation and a decline in functional fitness. Considering that hearing is fundamental in the socialization process and, consequently, for oral communication, any and all changes in auditory perception can trigger problems in social interaction with a negative impact on people’s lives. Objective To analyse the impact of noise on hearing and life quality of dentists in Paraná. Methods This is a descriptive observational, cross-sectional study carried out with forty dentists from southern Brazil. The research subjects underwent basic audiological evaluation and high frequency audiometry, in addition to answering two questionnaires, one about life quality (SF-36) and the other with data about the working conditions, knowledge and perceptions of dentists regarding the exposure to noise at work. Results Auditory changes suggestive of being induced by noise were observed in 15% of dentists. In high frequency audiometry, auditory alterations occurred in six professionals, and in four of them there was bilateral alteration. The SF-36 indicated median values of 62.57 for general health and 64 for vitality; 100 being the maximum score. It was found that 52.5% of dentists are aware of the effects of noise exposure on health, but only 5% declared using ear protectors during the exercise of their profession. Conclusion Early awareness of the effects of noise would bring more comfort and life quality to dentists, as well as less hearing problems.

Full textAbstract:
Although one of the most harmful factors to health is noise, it is often ignored in life cycle assessment (LCA) studies. Most researches regarding noise inclusion in LCA focus on the problem of transport noise, and very few works consider the impact of noise emitted by other sources. This study addresses the effects of noise generated by cogeneration plants. The main objective is to assess the environmental performance of the noise reduction system by considering the health effects of noise due to steam discharge as well as to compare the environmental loss associated with the production and disposal of a steam silencer with the benefits resulting from its application for noise reduction. A method to determine midpoint and endpoint human health indicators for a composition of noise emitted by intermittent stationary source and background noise is developed. The results indicate that the health benefit due to noise reduction is six orders of magnitude greater than the environmental loss. Human health indicators attributable to noise reduction in the residential zones under consideration span a wide range of disability adjusted life years (DALY)—0.16–136 DALY. The greatest values occur in the densely populated areas located close to the noise source. A formula is proposed to express annoyance of the residents of individual zones depending on their distance to the steam discharge source, its sound power level, and existing background noise level. Uncertainty and sensitivity analyses have been carried out assuming other conditions. Modifications of sound power level, noise reduction efficiency, steam discharge duration, and the silencer lifetime have not affected the overall conclusion drawn.

PURPOSE: To investigate the presence of auditory and nonauditory symptoms in professionals working in ambulances. METHODS: This was a descriptive cross-sectional study with a convenience sample. Thirty-six professionals working in mobile support units, including drivers and nursing technicians from two private urgency and emergency services in the city of Belo Horizonte, Minas Gerais, Brazil, participated in the study. A questionnaire containing 17 multiple-choice questions was applied to the participants with questions regarding life history and occupation, family history of hearing loss, use of medications, and presence of auditory and nonauditory symptoms, among others. The professionals answered the questionnaire individually, in their workplaces, and received help from the researcher to understand the content of questions, if needed. Data were statistically analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 16.0. RESULTS: The most reported auditory symptoms were tinnitus, intolerance to intense sounds, and ear plenitude. The most reported nonauditory symptoms were irritability, headache, talking difficulties in noisy environments, and sleep alterations. A difference (p≤0.05) was observed when the relation between self-perception of drivers and nursing technicians on hearing acuity, presence of tinnitus, irritability, and communication difficulty was analyzed. CONCLUSION: Auditory and nonauditory symptoms are frequent in workers from mobile support units. An association between the worker's symptoms and the performed function was also observed. The results indicate a need of developing preventive actions regarding general health, which are aimed at the preservation of hearing health and quality of life of these professionals.

Noise emission from individual vehicle largely contributes to city pollution and has serious health impact. The standards towards vehicle manufactures consists in pass-by testing with specific acceleration conditions which are not representative of all real driving. For the 2015/996 EU directive, the vehicle source model is inspired of the preceding pass-by standard with derived data represented the propulsion and rolling noise sources. Anyhow, those sources are underestimated due to driving behavior, aged and modified vehicle, road surface, meteorological conditions... The true data collection of vehicle pass-by would be interesting. Moreover, some of the countries are reflecting on how to fight against those extremely noisy vehicle exceeding noise limit with efficient monitoring systems. This paper presents an innovative tool able to detect, identify and quantify the noise emission of individual pass-by vehicle in real life traffic. It is based on the combination of array and video processing. Compared to the state of the art and thanks to MEMs technology, the system is optimized and designed to quantify the individual noise vehicle emission regarding standard with controlled measurement and accurate processing. If the conditions are not respected to properly qualify the pass-by regarding the system limits, the data are ignored. It aims at constructing large and accurate database useful to determine average noise levels and/or acceptable noise limits per vehicle category.
