Average Noise Level

Iron and steel factory workers in Tanzania are likely to develop noise-induced hearing loss (NIHL) due to exposure to high sound levels. Studies on hearing status in this population are lacking. The aims of this study were to determine prevalence of NIHL among iron and steel workers and compare hearing thresholds at different frequencies with a control group. We conducted a cross-sectional study among 221 iron and steel workers exposed to average noise level of 92 dB(A), compared with 107 primary school teachers recruited as controls and exposed to average noise level of 79.7 dB(A). We used a questionnaire-based interview to collect information on socio demographic characteristics and other confounding variables. Hearing loss was defined as hearing threshold levels ≥25 dB hearing loss in either ear at 3000, 4000 or 6000 Hz. The prevalence of hearing loss was significantly higher among the exposed group than among the controls, i.e. 48% and 31%, respectively. There were significant differences in hearing thresholds between the exposed and control groups at 3000, 4000, 6000, and 8000 Hz. Hearing loss was more frequent among workers exposed to higher noise levels than among the controls suggesting that iron and steel workers run a higher risk of developing hearing loss.

The Impact

AbstractNoise can have an impact on hearing loss. Changes in hearing thresholds due to noise are some temporary but others potentially permanent. The impact of hearing loss must be controlled so the quality of life will not decrease. A cross-sectional study to assess the quality and increasing knowledge about noise-induced hearing loss was implemented with lectures, discussions and a pre-test before the activity and a post-test after the activity to assess the knowledge development. The polling was conducted to assess the participants' attitudes and psychomotor skills. The study was followed by 77 participants, most of whom were aged 20-30 years, namely 23 (30%). It was found that 16 people (20%) had complaints of hearing loss, 18 people (24%) often used headsets and earphones, 18 (23%) people worked in noisy places. The average pre-test result was 35.06 (+13.72) and the post-test was 77.9 (+20.81). Comparison of pre-test and post-test results of hearing health education obtained different results (p < 0.0001) significantly. Noise-induced hearing loss is permanent deafness and cannot be treated with medicine or surgery. Prevention is the most important thing from noise-induced hearing loss. The counseling education about noise-induced hearing loss on community must always be performed as an prevention and early detection.Keywords: deafness, noise induce hearing loss, prevention, education AbstrakBising dapat berdampak terhadap gangguan pendengaran.

Dampak gangguan pendengaran harus dikendalikan agar tidak menimbulkan penuruna kualitas kehidupan. Studi cross sectional untuk menilai kualitas dan upaya peningkatan pengetahuan tentang gangguan pednegaran akibat bising dilaksanakan dengan ceramah, diskusi dan dilakukan pre test sebelum kegiatan dan post test setelah kegiatan untuk menilai peningkatan pengetahuan. Survei jajak pendapat dilakukan untuk menilai sikap dan psikomotor peserta. Studi diikuti 77 peserta, usia terbanyak di usia 20 – 30 tahun yaitu 23 orang (30%). Didapatkan 16 orang (20%) mengalami keluhan gangguan pendengaran, 18 orang (24%) sering menggunakan headset dan earphone,18 (23%) orang bekerja di tempat bising.  Hasil rata-rata pre test 35,06  (+13,72) dan rata-rata post test 77,9 (+20,81).

Tuli akibat bising merupakan tuli yang bersifat menetap dan tidak dapat diobati dengan obat maupun pembedahan, pencegahan merupakan hal yang terpenting dari tuli akibat bising atau noise induced hearing loss.Kegiatan edukasi penyuluhan gangguan pendengaran akibat bising harus senantiasa dilakukan di masyarakat sebagai upaya pencegahan dan deteksi dini.Kata kunci: Tuli, gangguan pendengaran karena bising, pencegahan, edukasi

Abstract Background Lifelong inflammation – known to be associated with many non-communicable diseases – has not been thoroughly investigated in hearing. We aimed to determine if glycoprotein A (GlycA), a novel biomarker of chronic inflammation, is associated with hearing acuity in mid-childhood and mid-life. Methods Population-based cross-sectional study within the Longitudinal Study of Australian Children with plasma GlycA and audiometry data (1169 children and 1316 parents). We calculated high Fletcher Index (mean threshold across 1, 2 and 4 kHz), defining hearing loss as threshold >15 decibel hearing level (dB HL) (better ear). Linear/logistic regression quantified associations of GlycA with hearing threshold/loss. Results Mean [standard deviation (SD)] high Fletcher Indices (dB HL) were 8.0 (5.7) for children and 13.1 (6.9) for adults, with 8.7% and 26.1% respectively showing hearing loss. 1-SD rise in GlycA (children 0.13 mmol/L, adults 0.17 mmol/L) predicted higher hearing thresholds for the lower individual frequencies [1 kHz: children β 0.8, 95% confidence interval (CI) 0.3–1.3; adults β 0.8, 95% CI 0.2–1.4]. This same pattern was evident for the high Fletcher Index (children β 0.7, 95% CI 0.3–1.1; adults β 0.8, 95% CI 0.3–1.4). This translated into 1-SD rise in GlycA predicting adult hearing loss [odds ratio (OR) 1.2, 95% CI 1.0–1.5] with similar but attenuated patterns in children. Conclusions GlycA is associated with poorer hearing by mid-childhood. This potentially reframes hearing loss as a life-course condition with inflammatory antecedents common to other non-communicable diseases. Replication and mechanistic studies could inform causal inference and early prevention efforts.

Study Setting

Objectives: Occupational noise induced hearing loss (ONIHL) is considered an important reason responsible for disability around the world. As industrial workers are frequently exposed to occupational noise, sensorineural hearing loss (SNIHL) is commonly found in this set of population. This study was conducted to determine the frequency of noise induced hearing loss (NIHL) in industrial workers of Multan. Study Design: Descriptive, cross-sectional study. Setting: Department of Otorhinolaryngology, Nishtar Hospital, Multan. Period: 16th April 2018 to 15th October 2018. Material & Methods: A total of 316 industrial workers of age 25-65 years and both genders were included. Audiometric testing was performed in a sound free room where calibrated digital audiometer ALPS AD 2100 was used. Hearing threshold was obtained for both ears at 250-8 kHz. NIHL was noted. Results: Mean age was 45.56 ± 10.95 years. Most patients, 170 (53.80%) were 25-45 years of age. There were 188 (59.49%) male and 128 (40.51%) female. Mean duration of experience was 11.14 ± 5.86 years. NIHL was found in 95 (30.06%) patients. Conclusion: Frequency of NIHL among industrial workers is high. Factory owners and workers should consider adopting preventive and safety measures to control noise induced hearing loss.
