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.

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.

Abstract Background Significant sex differences exist in hearing physiology, while few human studies have investigated sex differences in noise-induced hearing loss (NIHL), and the sex bias in previous studies resulted in inadequate female data. The study aims to investigate sex differences in the characteristics of NIHL to provide insight into sex-specific risk factors, prevention strategies and treatment for NIHL. Methods This cross-sectional study included 2280 industrial noise-exposed shipyard workers (1140 males and 1140 females matched for age, job and employment length) in China. Individual noise exposure levels were measured to calculate the cumulative noise exposure (CNE), and an audiometric test was performed by an experienced technician in a soundproof booth. Sex differences in and influencing factors of low-frequency (LFHL) and high-frequency hearing loss (HFHL) were analyzed using logistic regression models stratified by age and CNE. Results At comparable noise exposure levels and ages, the prevalence of HFHL was significantly higher in males (34.4%) than in females (13.8%), and males had a higher prevalence of HFHL (OR = 4.19, 95% CI 3.18 to 5.52) after adjusting for age, CNE, and other covariates. Sex differences were constant and highly remarkable among subjects aged 30 to 40 years and those with a CNE of 80 to 95 dB(A). Alcohol consumption might be a risk factor for HFHL in females (OR = 3.12, 95% CI 1.10 to 8.89). Conclusions This study indicates significant sex differences in NIHL. Males are at higher risk of HFHL than females despite equivalent noise exposure and age. The risk factors for NIHL might be different in males and females.
