Resumen

The aim of this study was to find out the Hearing Aid Assistance Program for the Elderly in Pangkalan Balai Village, Banyuasin III District using qualitative methods. The results of the study show that the Hearing Aid Assistance Program for the Elderly has not been implemented properly due to several obstacles in the distribution of hearing aids for the elderly. The productivity dimension, in terms of service, the attitude of the Banyuasin district social service staff is sometimes not responsive in handling requests for hearing aid assistance for the elderly. The mechanism dimension, in terms of distribution procedures, is basically the main activity carried out by the Banyuasin Regency Social Service in distributing hearing aid aid for the elderly in Pangkalan Balai Village, namely meeting the need for aids for people in need. The responsiveness dimension, in terms of community response, is quite good. The distribution of hearing aids for the elderly in the Pangkalan Balai Village by the Banyuasin Regency Social Service had a positive impact. The targets of the results to be achieved by the Banyuasin District Social Service for the sector of providing and distributing hearing aid assistance to the elderly in Pangkalan Balai Village are that hearing aid assistance services are met evenly for a number of elderly people.

Resumen

The purpose of this questionnaire study was to evaluate the existing knowledge of binaural hearing and the attitudes and practices of prescribing bilateral hearing aids amongst otolaryngologists in the United Kingdom. Of the 950 questionnaires sent to the current members of the British Association of Otolaryngologists and Head and Neck Surgeons (BAO-HNS), there were 591 respondents (62 per cent). The true response rate with completed questionnaires was 59 per cent. Eighty-one per cent of the respondents were aware of the importance of binaural hearing and had a positive attitude towards binaural fitting. The practice of bilateral hearing aid prescriptions was found to be poor amongst all grades on the NHS (less than 10 per cent of all hearing aid prescriptions). This practice in the private sector was variable, dependent largely on patient preference and affordability. The practice of binaural prescription was higher for patients in the paediatric age group than amongst adults. Two common indications for hearing aid prescriptions for unilateral deafness were otitis media with effusion in children (23 per cent of respondents) and for tinnitus masking in adults (12 per cent of respondents). Many otolaryngologists believed that there was not enough evidence to support bilateral bone-anchored hearing aid implantation and bilateral cochlear implantation. Ninety-four per cent of the respondents believed that binaural hearing was as important as binocular vision.

Resumen

The American Speech-Language-Hearing Association (ASHA) defines telepractice as the application of telecommunications technology to deliver professional services at a distance by linking clinician to client; or clinician to clinician for assessment, intervention, and/or consultation (ASHA, 2005a). Telepractice has become a standard delivery process for the medical community. ASHA has recognized telepractice as a viable and appropriate venue for audiologist. They have provided a position statement to guide audiologists using telepractice. The advent of high speed Internet and computerized testing equipment has increased the capability of audiologists to use telepractice technology. Research has shown significant evidence that telepractice could be used to provide many aspects of audiological assessment and treatment. There are three types of telepractice technology that can be used to aid the audiology practice: synchronous, which uses real time technology, asynchronous, which uses store-and-forward technology, and hybrid, which is a combination of both. Telepractice could be a valuable resource for public sector audiologists in the near future. Newborn hearing screening and educational audiology programs will likely benefit greatly from the use of telepractice. If the advances in technology continue at the current pace, telepractice will be poised to help provide services to difficult-to-reach patients all over the world.

Resumen

Objectives: To report the clinical results of a bone-anchored hearing aid (BAHA) programme in a district general hospital, compared with those in an established, large, university teaching hospital centre.Design: A retrospective postal questionnaire sent to BAHA patients, with two month waiting time and one reminder, combined with case note analysis. Results compared by appropriate statistical tests with published outcomes data from the largest UK series.Setting: Public sector (National Health Service) district general hospital, England. Catchment population: 300 000 (mixed rural and small towns).Participants: Case note analysis of sixty-three patients implanted between 1994 and 2003 (age range, six to 88 years). The commonest indication was chronic otitis media, with inability to wear a conventional hearing aid. Otitis externa, otosclerosis and sensorineural hearing loss were other indications. The questionnaire was sent to 59 patients who had worn their aid for at least six months; it was returned by 41 (69 per cent).Main outcome measures: Glasgow benefit inventory (GBI, change in health status following otolaryngological intervention); incidence of complications.Results: Bone-anchored hearing aid implantation significantly improved quality of life as measured by the GBI (p < 0.001). The degree of improvement was similar to that achieved in Birmingham by Proops et al. (p > 0.05, chi-squared test). Minor temporary skin infection was common (33 per cent). Thickening of the skin around the implant occurred in 17 per cent. One implant (2 per cent) failed. There were no serious complications.Conclusion: The BAHA is a safe, reliable and effective treatment for selected patients. A successful BAHA programme can be run in a district general hospital.

Resumen

The increasing use of multimedia in learning resources in higher education poses a challenge for learners with hearing disabilities, unless these are accompanied by transcripts or captions. This paper reports on a small study where six Automatic Transcription Software (ATS) were analysed for their accuracy. Although economical and timesaving, at present, it seems an automatically generated transcript is not yet accurate enough to be an accessibility aid for the subjects relating to built environment sector.

Resumen

Evaluating risks associated with multiple occupational exposures is no easy task, especially when chemical and physical nuisances are combined. In most countries, public institutions have created databases, which gather extensive information on occupational exposures or work-related diseases. Unfortunately, these tools rarely integrate medical and exposure information, and, above all, do not take into account the possible adverse effects of co-exposures. Therefore, an attempt to exploit and join different existing databases for the assessment of the health effects of multiple exposures is described herein. This case study examines three French databases describing exposures to noise and/or ototoxic chemicals (i.e., toxic to the ear) and the incidence rate of occupational deafness in different sectors. The goals were (1) to highlight occupational sectors where the workers are the most (co)exposed and (2) to determine whether this approach could confirm the experimental data showing that this co-exposure increases the risk of developing hearing loss. The results present data per occupational sector exposing workers to noise only, ototoxic chemicals only, noise and ototoxic chemicals, and neither of these two nuisances. The ten sectors in which the proportion of exposed workers is the highest are listed. This analysis shows that the rate of hearing loss in these sectors is high but does not show an increased incidence of hearing loss in co-exposed sectors.

Resumen

Cochlear implants (CI) are electronic devices that are surgically implanted in children with profound hearing loss to enable them experience sensation of sound. U.S was the first to approve CI surgeries for children in 1990 and the minimum age was lowered to 12 months by U.S Food and Drug Administration by 2002.1 Growing numbers of evidence has demonstrated positive outcomes of CI in language and communication by improving children’s speech perception and speech production.2 Outcomes of CI are neither instant nor irrefutably assured and demands continuous effortful habilitation process to prove this surgery a wise decision.3,4 Evidence shows great variability in outcomes following CI which indicates that children may continue to show hearing and communication problems.5 Long-term habilitation processes of CI and continued exposure to difficulties generate many stressors to parents along with challenges to parental role. Furthermore, to ensure success of CI, parents play a key role by complying with whole rehabilitation process. Therefore any factor that can cause stress for parents and destroys their mental health, can affect child’s progress. Literature reveals that psychological distress is more experienced among parents of children with CI not only in comparison to parents of normal hearing children6 but also do parents of deaf and conventional hearing aid users.7 In Pakistan CI programme began in 2000 and at that time due to financial constraints only few patients were able to afford this and faced many difficulties in its long term rehabilitation process.8 Currently many hospitals in liaison with international companies are offering CI surgeries with habilitation services. Some of those hospitals are Dow University of Health Sciences Karachi, Capital Development hospital Islamabad, Combined Military Hospital Rawalpindi, Bahria International Hospital Lahore and Central park hospital Lahore. Many schemes also provide free cochlear implant surgery services with one year fund for habilitation services i.e. audiological services and speech therapies. It is commendable that services to patients of CI in Pakistan are growing at exponential rate from selection of CI candidate to habilitation process post-surgery, but parallel to that parents’ increasing stress level affecting their psychosocial life cannot be ignored. It has been observed that at first hand CI poses great financial burden that can continue to upheaval at any stage of life even after bearing expense of costly CI surgery, when any piece of device gets damaged or need repair. Even if insurance is sought it requires depositing minimum eighty thousand rupees per year that is only affordable for high economic strata. Services of CI surgeries are only offered in few big cities and for every mapping and follow up. Patients from far-flung areas are required to travel long distances and for life long they become dependent on their CI panel and/or company no matter how many difficulties, bad attitude and unprofessional habilitation services they witness and face. Parents victimhood shout out that many public and private sector institutes claim that they provide Auditory Verbal Therapy (AVT) but in actual these institutes are filled with trainees who themselves do not know the exact approach and trains child on total communication approach that make child dependent on gestures, lip reading and loud voice from messenger that overall affects typical milestones of listening development. Such truths get exposed when child was assessed by some expert speech therapist. Parents also reported that at times remarks of audiologist get stressful when within few months of implant they compare their child with some other child and states that the other one has got much verbal as compared to your child or why he/she hasn’t started speaking yet. In opinion of parents who have gone through this long journey, many audiologists except few don’t seem to be aware of typical listening milestones. Many parents reported that speech therapy is a long-term process which itself carries financial load but even it is taken, you can never be assured that therapist is following standardized steps or not. Some parents reported that we immediately got happy when our child started uttering many word within few therapy sessions soon after device switched on but after long time they got to know that these words are not in child’s listening but only taught with lip-reading for immediate results. When conflict arises in opinions and practices of professionals serving CI patients, then conflict among parents of CI children also arise when each parent gets believer of different professional opinion. This difference of opinion consequently leads to stress in their marital and family life. Increased stress level among parents of cochlear implanted children is an indication of serious threat to the mental and emotional health of a family system rearing such child. Studies should be conducted to figure out all possible factors rooting this stress. Though, it is not possible for multidisciplinary team (MDT) of CI to lower the stress that arises secondary to expense of CI but stressors that up thrust due by malpractice and inappropriate guidance of members in MDT should be eradicated by ensuring provision of trained professionals.

"The Combined Impact of Hand-Arm Vibration and Noise Exposure on Hearing Sensitivity of Agricultural/Forestry Workers—A Systematic Literature Review".

Resumen

Hand-arm vibration (HAV), which potentially causes vibration white finger (VWF), and occupational noise are serious issues in the agricultural and forestry industries. Generally, agricultural workers operate as single-family/small businesses and thus are exempted from Occupational Safety and Health Administration (OSHA) regulations/laws for noise and HAV otherwise applicable to other industries in general. The agricultural/forestry sectors are at increased risk as working hours are longer than a typical 8-h work shift putting them at greater risk of hearing loss. The study was conducted to assess the possible association between hearing sensitivity on combined exposure to noise and hand-arm vibration. A systematic literature review was conducted on exposure to noise and HAV in the agricultural/forestry sector and the resulting impacts on hearing. The peer-reviewed articles in English were searched with 14 search words in three databases of PubMed, Ergo Abstracts, and Web of Science without any filter for the year for fully available article text. The database literature search resulted in 72 articles. Forty-seven (47) articles met the search criteria based on the title. Abstracts were then reviewed for any relationship between hearing loss and hand-arm vibration/Raynaud’s phenomenon/VWF. This left 18 articles. It was found that most agricultural workers and chainsaw workers are exposed to noise and VWF. Hearing is impacted by both noise and aging. The workers exposed to HAV and noise had greater hearing loss than non-exposed workers, possibly due to the additive effect on temporary threshold shift (TTS). It was found that VWF might be associated with vasospasm in the cochlea through autonomous vascular reflexes, digital arteries narrowing, vasoconstriction in the inner ear by noise, ischemic damage to the hair cells and increased oxygen demand, which significantly affects the correlation between VWF and hearing loss.

Resumen

Literature into exposure to occupational noise in developing countries suggests that the prevalence of occupational noise–induced hearing loss is still high. There is also evidence that the mining industry is aware of this epidemic; however, the efforts to curb occupational noise–induced hearing loss are currently unsuccessful. Therefore, the aim of this study was to explore and document current evidence reflecting trends in the management of occupational noise–induced hearing loss in the mining industry in Africa from 1994 to 2016. A systematic literature review was conducted in line with the Cochrane collaboration guidelines and Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Electronic bibliographic databases such as ScienceDirect, PubMed and Scopus MEDLINE were searched. A total of 1212 titles and abstracts were identified; of which only nine papers formed part of this study. The results indicated that there is a dearth of research on the management of occupational noise–induced hearing loss in Africa. The limited research on the management of occupational noise–induced hearing loss focuses on some aspects of the hearing conservation programme pillars and not on all the pillars as suggested by some scholars in the field. Furthermore, these studies had small sample sizes thereby, minimizing their generalization. There is therefore a need for more studies on the management of occupational noise–induced hearing loss in the mining sector, as there is evidence to suggest that occupational noise–induced hearing loss in African countries is still on the rise.

Resumen

The extent to which open learning is being adopted by South African Technical and Vocational Education and Training (TVET) institutions in general and, more specifically, to support students with disabilities (SWDs) is not known. The aim of this study is to better understand the ways in which one ‘disability-friendly’ TVET college has opened up learning to students with mobility, visual, hearing, communication, intellectual, emotional and multiple limitations, impairments and/or disabilities. Two senior managers and four staff members were interviewed in this qualitative study undertaken amid the COVID-19 pandemic. Fraser’s (2005) conception of social justice as ‘parity of participation’ is used as a lens to untangle the economic, cultural and/or political injustices faced by SWDs as well as the staff who endeavour to support them. Several national government and institutional structural arrangements, institutional cultural conventions and individual activities have helped to ameliorate some economic and even transform some cultural injustices. However, more synergy and proactive interventions are required between policies and financial provision at national and municipal levels to ensure parity of participation of SWDs. These insights are applicable for implementation at the institution, in the TVET sector more broadly, for consideration by policymakers at the Department of Higher Education and Training, the National Student Financial Aid Scheme and Sector Education and Training Authorities as well as by employers seeking to increase access, progression and success of SWDs.

Resumen

Web 2.0 technologies—what we prefer to call the “Interactive Web”—have become frequently used tools in the public sector. These tools include social networking applications such as Twitter, Facebook, Wikis, or RSS feeds. Public sector agencies are using blogs to communicate information on public hearings, wikis to coordinate work or share expertise and intelligence information, and social networking sites to communicate with citizens. These kinds of applications create a public sector paradox. On the one hand, they have the potential to create opportunities related to key public sector issues of transparency, accountability, communication and collaboration, and to promote deeper levels of civic engagement. On the other hand, information flow within government, across government agencies, and between government and the public is often highly restricted through regulations and specific reporting structures, and therefore usually delayed through the filter of bureaucratic constraints. The authors provide an overview of drivers encouraging the adoption of Interactive Web applications, but also transformative organizational, technological, and informational challenges ahead that might lead to resistance to that change.

Resumen

Almost 460 million world people live with moderate to severe hearing loss (HL), with noise the most common cause, particularly in the workplace. Noise-induced HL is still one of the most prevalent recognized occupational diseases, but in Italy, it is no longer at the first ranks, thanks to technical and organizational solutions adopted to reduce noise in the work environment after 2008. In particular, Italian surveillance system data show that Construction is the work sector in which HL is most present (28% of cases), followed by Manufacture (17%). HL can compromise social life, causing isolation, frustration, depression, and even cognitive decline, while in the workplaces could affect workers’ safety, representing an important injury risk factor. The use of hearing aids (HA) represents an effective preventive action. In Italy, there are at least 7 million hearing-impaired people, but only 29.5% wear an HA (2018 data). Their use appears to be more widespread in the older age groups, while the least use is found from 45 to 64 years (20.8%) which refers to professionally active people. Many aspects prevent the use of an HA, among these, technical and psychological reasons. The objective of this study is to evaluate the degree of comfort/discomfort and the perceived benefit of using an HA, particularly in working environments.MethodsAn ad hoc questionnaire consisting of 10 questions, five on the working sphere and five on perception, was developed. The former investigated the acoustic comfort of the work environment, use of HA, hearing protectors, accessories, and the information received on the correct use of HA at work; the second investigated the satisfaction of the prosthetic solution, the improvement in the perception of speech or the sounds direction and danger signals to avoid accidents at work. The answer options for each question were yes / sometimes / no. Further information on gender, age, type of job, years of work, type of HA and years of use, type of hearing damage, was collected. The professions were grouped into seven categories: construction workers, freelancers, health professions, teachers, office workers, traders, others, which were further classified on noise exposure and hearing risk into High risk (construction workers), Medium risk (teachers, traders), Low risk (freelancers, health professions, office workers). The results were statistically analyzed.ResultsThe questionnaire was administered to 141 workers (55 females and 86 males) with an average age of 57 years (minimum 21, maximum 82). The sample shows prevalently bilateral sensorineural HL, works for about 30 years, wears an HA from 6 years, mainly “in the ear” type (77%), mostly employed as freelancers (21%), office workers (19%), construction workers (18%).For high-risk employees, the use of an HA with personal protective equipment has been discussed, taking into account the issue regarding the protection of these prosthetic workers in noisy work environments. The results show that special attention should be paid to the optimization of the prosthesis for this category of workers, most acoustically exposed, taking into account their comfort, perceived safety, and satisfaction.

Resumen

The elaboration is the study is to examine the difference in the sound level in the air handling units made by the same producer. These units are of the same design parameters and components, and supply air and exhaust air. The only difference is mounted engines. Tested air handling units are equipped with an engine type EC, and traditional direct drive, controlled by an converter. Sound level measurements were carried out in the ducts supply air ventilation system at a distance of 1 m from the air handling unit and for the unit at a distance of 2 m from the inspection door of the fan section of the supply, with 3 settings efficiency of units 30%, 60% and 90%. Tested headquarters are located inside the building. Excessive noise has a negative effect on the human body, resulting in fatigue, difficulty in learning and concentration, impaired orientation, annoyance, increase in blood pressure, headaches, dizziness, and in the worst case of temporary or permanent hearing loss. For this reason it is very important to protect against noise. Therefore, it was these studies.

Resumen

Germany has decided to fundamentally transform its whole energy system. The transformation requires numerous infrastructure projects that are conflict-prone [1]. To handle conflicts, involved companies are expected to use legally prescribed public participation procedures (formal) as well as non-legally binding participation processes (informal). Public participation can occur on three intensity levels: information, consultation, and cooperation [2]. Little research has been done on how conflict communication can be used at different participation levels. This paper aims on a deeper understanding of how conflict communication formats are perceived by people living in so-called energy regions, i.e., regions undergoing an intensive energy transformation. It focuses on how they retrospectively evaluate their potential for conflict management, and what recommendations they derive from this knowledge.This paper presents selected outcomes of a study conducted in the large-scale project ENSURE, funded by the German Federal Ministry of Education and Research. The project aims on solutions for the German energy transition. The study combines in-depth interview and pre-questionnaire. The literature-based interview guideline covers two question complexes: (1) background, remit, and experience, (2) conflict communication (occurrence of conflict; conflict triggers and resolutions; potential of communication formats; quality criteria; challenges of distance conditions). In the pre-questionnaire, respondents were asked to rate the potential of formats of participation levels for conflict management (1 = very suitable; 6 = not suitable at all). For each level, formats frequently named in the literature were given [3]. In the in-depth interviews, participants were asked to comment on their ratings. In addition, they were asked to recall two infrastructure projects they had experience with and indicate which formats had been used particularly well or poorly? The participants were contacted using a stakeholder list provided by the project consortium. The participants (n=12; nine male, three female) live in the federate state Schleswig-Holstein and have experience with infrastructure projects in the energy and/or mobility sector. All are well-informed about the region. Most of them (n=8) are involved in environmental protection organizations or in local politics, e.g., in regional development committees. Interviews were conducted digitally in 2021. The data were anonymized, transcribed, analyzed qualitatively (two coders; overall categories: 247) as well as quantitatively.Conflict communication formats were mostly used on the information level. The best ratings are given to consultation level formats (Ø = 2.2). At the information level, information events are rated as most suitable (Ø = 1.3). At consultation level, resource-intensive personal talks with those affected are recommended (Ø = 1.3). Respondents favor integrating levels of participation and formats, e.g., consultation processes as part of information events. At cooperation level, mediation is best rated (Ø = 1.9). The respondents address factors influencing the suitability of formats for conflict management. Some formats are strongly topic-dependent, e.g., an expert hearing is particularly suitable if a topic generates fears. Other factors are the target group, the local context (city/rural) or the setting (private/public). The format choice should consider the project size and phase.Further research should examine the impact of the factors named above and how conflict communication can function under distance conditions (COVID-19 pandemic).Literature[1] Renn (2015): Aspekte der Energiewende aus sozialwissenschaftlicher Perspektive.

Resumen

In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Mesa Verde National Park (MEVE). Between July and August 2015, as well as February and March 2016, three acoustical monitoring systems were deployed throughout the park, however one site (MEVE002) stopped recording after a couple days during the summer due to wildlife interference. The goal of the study was to establish a baseline soundscape inventory of backcountry and frontcountry sites within the park. This inventory will be used to establish indicators and thresholds of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Additionally, results of this study will help the park identify major sources of noise within the park, as well as provide a baseline understanding of the acoustical environment as a whole for use in potential future comparative studies. In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an anemometer to collect wind speed and a digital audio recorder collecting continuous recordings to document sound sources. In this document, “sound pressure level” refers to broadband (12.5 Hz–20 kHz), A-weighted, 1-second time averaged sound level (LAeq, 1s), and hereafter referred to as “sound level.” Sound levels are measured on a logarithmic scale relative to the reference sound pressure for atmospheric sources, 20 μPa. The logarithmic scale is a useful way to express the wide range of sound pressures perceived by the human ear. Sound levels are reported in decibels (dB). A-weighting is applied to sound levels in order to account for the response of the human ear (Harris, 1998). To approximate human hearing sensitivity, A-weighting discounts sounds below 1 kHz and above 6 kHz. Trained technicians calculated time audible metrics after monitoring was complete. See Methods section for protocol details, equipment specifications, and metric calculations. Median existing (LA50) and natural ambient (LAnat) metrics are also reported for daytime (7:00–19:00) and nighttime (19:00–7:00). Prominent noise sources at the two backcountry sites (MEVE001 and MEVE002) included vehicles and aircraft, while building and vehicle predominated at the frontcountry site (MEVE003). Table 1 displays time audible values for each of these noise sources during the monitoring period, as well as ambient sound levels. In determining the current conditions of an acoustical environment, it is informative to examine how often sound levels exceed certain values. Table 2 reports the percent of time that measured levels at the three monitoring locations were above four key values.
