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.

Abstract Background Occupational noise exposure was related to cardiovascular disease, of which dyslipidemia was an important inducement. This study investigated the relationship between occupational noise exposure and dyslipidemia. Methods Four hundred ninety-two occupational noise-exposed workers and 664 non-exposed workers were recruited to conduct environmental noise tests and personal occupational physical examinations. A lasso-logistic regression model was used to estimate the relative risk of dyslipidemia. A restricted cubic spline was used to estimate the association between noise exposure years and dyslipidemia after adjusting for potential confounding factors. Results A crude association was observed between the occupational noise exposure (75–85 dB(A)) and dyslipidemia. After adjusting for confounding factors, there was a non-linear relationship between noise exposure years and dyslipidemia (P for non-linearity =0.01). Workers exposed to 75–85 dB(A) for 11 to 24.5 years had a higher risk of dyslipidemia than non-exposed workers. Conclusions A positive and non-linear exposure-response relationship was found in workers exposed to 75–85 dB(A) whose exposure years were between 11 and 24.5. Workers had the highest risk of dyslipidemia when exposed for 13.5 years.

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.
