Introduction: Noise Induced Hearing Loss (NIHL) is an occupational health hazard linked with noise exposure of more than 85 dB. Aircraft noise and other occupational noise exposure cause military aviators more susceptible to NIHL than commercial jet pilots. Aim: To find out the prevalence of noise induced hearing loss among different military aircrew population with special emphasis on identifying the associated risk factors. Materials and Methods: This cross sectional study was conducted on Kuwait Air force pilots those who came for annual medical checkup from July 2010 to July 2012. Audiometry of all subjects was done by ENT specialist and necessary data were collected by structured questionnaires. All data were analyzed by SPSS (Statistical Package for the Social Sciences) version 17.0 Results: Out of 221 aircrew 32 (14.48%) developed NIHL. Hearing loss was mild to moderate and predominately at high frequencies. Most affected group was helicopter pilots. Pilots of more than 40 years of age and those who had more than 1000 flying hours had mean hearing threshold more than other groups. The right ear was affected in majority of cases than left ear. Conclusion: Noise exposure to aircrew is inevitable so hearing loss prevention strategies might play a pivotal role to save aircrew hearing. Active surveillance of hearing protection practices might have beneficiary effect. Steps can be taken for early detection of NIHL and hearing conservation program.

Abstract: Hearing loss is the inability of a person’s sense of hearing in listening range of sound that can still be heard by people with normal hearing. With the growing popularity of entertainment venues (discos, karaoke, music concerts, internet cafes, etc.) as well as the use of portable music player, leisure noise have become the primary source that causing increased incidence of adolescent noise induced hearing loss (NIHL). Attitudes towards noise needs to be assessed at a young age, this is because the attittude is the basis of behavior, and behavior (towards leisure noise) can affect the amount of noise exposure of each person. Chronicity of NIHL symptoms often make adolescent tends to ignore the serious long-term problem that can arise and not take steps to resolve it. Objective: The purpose of this study is to obtain data from students of Manado 2nd Vocational Senior Secondary School concerning attitudes towards noise. Method: This research used descriptive observational with cross-sectional study. The subjects are students of Stone Concrete’s majors in Manado 2nd Vocational  Senior Secondary Schoolthat have passed initial hearing screening. Result: Of the 20 respondents who willingly take part in this research, obtained 5 respondents (25%) had negative attitude, 10 respondents (50%) had neutral attitude, and 5 respondents (25%) had positive attitude. From audiometric examination, obtained 4 respondents had a mild decreased in hearing threshold. Of the 4 respondents, 2 (50%) of them had a neutral attitude and 2 other respondents (50%) had positive attitude. Conclusion: Respondents with positive attitude towards noise are vulnurable to hearing threshold changes caused by daily noise exposure.Keywords: adolescent, hearing, noise, attitudes towards noise     Abstrak: Gangguan pendengaran merupakan ketidakmampuan indra pendengaran seseorang dalam mendengarkan rentang suara yang masih dapat didengar oleh orang dengan pendengaran normal. Semakin berkembangnya popularitas dari tempat-tempat hiburan (diskotik, karaoke, konser musik, warung internet, dan lain sebagainya) serta penggunaan pemutar musik portabel telah menjadi sumber peningkatan angka kejadian gangguan pendengaran akibat bising (GPAB) pada usia muda. Sikap terhadap kebisingan perlu dinilai pada usia muda, hal ini dikarenakan sikap merupakan dasar dalam berperilaku, dan perilaku (terhadap kebisingan sosial) dapat mempengaruhi derajat paparan bising masing-masing orang. Kronisitas dari gejala (GPAB) membuat kaum muda kurang menanggapi serius masalah-masalah jangka panjang yang dapat ditimbulkan, serta mengambil langkah untuk mengatasinya. Tujuan: Tujuan penelitian ini adalah untuk memperoleh data sikap terhadap kebisingan pada siswa sekolah menengah kejuruan (SMK) Negeri 2 Manado. Metode Penelitian:Penelitian ini merupakan penelitian deskriptif observasional dengan menggunakan metode cross-sectional. Subjek penelitian adalah siswa jurusan Teknik Konstruksi Batu Beton (TKBB) SMK Negeri 2 Manado yang sudah melewati screening pendengaran awal. Hasil: Dari 20 responden yang bersedia menjadi responden penelitian, didapatkan 5 responden (25%) mempunyai sikap negatif, 10 responden (50%) mempunyai sikap netral, dan 5 responden (25%) mempunyai sikap positif. Dari pemeriksaan audiometrik, didapatkan 4 responden mengalami penurunan ambang dengar derajat ringan. Dari 4 responden tersebut, 2 (50%) diantaranya mempunyai sikap netral dan 2 responden (50%) mempunyai sikap positif. Simpulan: Responden yang bersikap positif terhadap bising (pro-bising) rentan terhadap terjadinya perubahan ambang dengar yang akibatkan oleh paparan kebisingan sehari-hari.Kata kunci: usia muda, pendengaran, bising, sikap terhadap kebisingan

Introduction.Although quarry operations have high economic significance, the effects they cause to the workers in terms of excessive noise production cannot be overlooked. This cross-sectional study assessed the extent of noise exposure and its influence on hearing capabilities among quarry workers in Ashanti region.Methods. The study involved 400 workers randomly selected from five quarries in Ashanti region from April to June 2012. Data was collected using structured questionnaires, physical examination, and audiological assessments. A logistic regression model was fitted to assess independent predictors of hearing loss.Results. All the machines used at the various quarries produced noise that exceeded the minimum threshold with levels ranging from 85.5 dBA to 102.7 dBA. 176 (44%) of study respondents had hearing threshold higher than 25 dBA. 18% and 2% of these were moderately (41–55 dBA) and severely (71–90 dBA) impaired, respectively. Age, duration of work, and use of earplugs independently predicted the development of hearing loss. Use of earplugs showed a protective effect on the development of hearing loss (OR = 0.45; 95% CI = 0.25, 0.84).Conclusion.This study provides empirical evidence on the extent of damage caused to quarry workers as a result of excessive noise exposure. This will support the institution of appropriate protective measures to minimize this threat.

Background: A few studies have investigated the interaction between exposure to road traffic noise, air pollutants, and cardiovascular disease (CVD), but their results were inconsistent. This cross-sectional study investigated whether road traffic noise, particulate matter with dynamic diameter less than 10 μm (PM10) and nitrogen dioxides (NO2) exposure were independently associated with the risk of CVD. Methods: We recruited 663 volunteers who had been living near main roads for more than three years in 2008. Information concerning the subjects’ home addresses was combined with noise measurements at 42 locations and annual average of air pollutants from 2 monitoring stations to estimate individual exposure. Multivariate logistic regression was used to calculate the odds ratio (OR) for diagnosed CVD, adjusting for potential confounders and co-exposure. Results: Only per 5-dBA increase in road traffic noise was significantly associated with elevated risk of CVD (adjusted OR = 2.23, 95% confidence interval (CI) = 1.26–3.93) in the single-exposure models. Such association was aggravated (adjusted OR = 2.96, 95% CI = 1.41–6.23) after adjustment for total traffic and PM10 or NO2 in the two-exposure models. Conclusions: Road traffic noise exposure may be associated with the increasing prevalence of CVD. No synergistic association was observed between co-exposure to noise and air pollutants and the risk of CVD.

Introduction: Simultaneous exposure to noise and dust may have detrimental health effects. This study was conducted to determine the effect of exposure to noise and dust on oxidative stress. Methods: In this cross-sectional study, 82 employees of two livestock and poultry feed factories in Golestan Province, Iran, were selected as the exposed group and 82 office workers were selected as the control group. Occupational noise and dust exposure were measured using a dosimeter, sampling pump, and vinyl chloride filter. Oxidative stress was determined by measuring the levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in blood samples. T-tests, one-way analysis of variance, and multivariate linear regression were used to analyze the data. Results: The levels of MDA and SOD in the exposed group were significantly higher and lower than the control group ( p < 0.001), respectively. The results showed the subgroup with both over the threshold dust and noise exposure had the highest MDA levels. The SOD level among those exposed to noise more than the recommended level, in the subgroup with more dust exposure, was significantly less than the subgroup with low noise exposure ( p = 0.017). Conclusion: Noise and dust exposure probably increase the level of oxidative stress by increasing the level of lipid peroxidation (MDA) and reducing the level of antioxidant enzymes (SOD).

Objectives. This study investigated the hearing loss characteristics among occupational noise exposure workers with hypertension and the link between hypertension and hearing loss when exposed to occupational noise. Methods. A total of 267,766 occupational noise-exposed workers were enrolled, including 29,868 workers with hypertension and 240,165 without hypertension. Hypertension was diagnosed according to WHO criteria. Hypertension was classified into four grades based on blood pressure. Assessment of hearing was performed through measurement of an unadulterated tone threshold at different frequencies, which ranged between 250 and 8,000 Hz. Results. A substantial link was observed to exist between hypertension and the increment in the hearing limit. The increase in the hearing threshold was substantially higher among those having grade 2 hypertension. Conclusion. The current investigation suggested patients with hypertension exhibit a substantial rise in hearing loss in comparison with patients without hypertension. The rise in hearing loss was significant in patients with grade 2 hypertension. Efficient and practicable measures are required to decrease the hearing loss in workers with hypertension and work-related noise exposure.

Occupational Noise Exposure

ABSTRACT Purpose: to determine the auditory effects of noise exposure from recreational and occupational sources among dentistry students. Methods: forty-two dentistry students, routinely exposed to occupational noise, and 72 students from other health science schools were recruited (control group). Audiometric testing, otoacoustic emissions and questionnaires to assess recreational and occupational noise were applied to the sample. The presence of a notch was determined for each participant audiometry´s test based on the criteria proposed by Coles et al. Differences in notch prevalence were analyzed by applying univariate regression models as well as a multivariate model adjusted by covariates. Results: non-significant differences in auditory thresholds between groups were found. The controls exhibited a significantly higher prevalence of a notch at 4 kHz than the group exposed to noise. However, the differences were not statistically significant in the multivariate model adjusted by recreational noise exposure. Conclusions: the occupational noise exposure was not significantly associated to auditory system dysfunction. In addition, the differences in notch prevalence could be related to recreational noise exposure.
