“…In Nepal, the prevalence among workers in a steel factory was comparable to our study, i.e., 40% and 46% for the right and left ear, respectively. However, the study excluded workers over 45 years and information on factory characteristics were not available [35]. Another study done in Nepal among 115 small-scale metal industry workers and 123 controls found lower prevalence for the exposed (30%) and only 4% for the controls [36].…”

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.

“…Traditionally, workplace noise is regarded as a hazard linked to heavy industries such as the steel industry and associated with noise-induced hearing loss (NIHL). Currently, in terms of occupational health and safety, it is accepted that noise is hazardous to workers’ health in many areas of employment and by different means 1,2. Occupational NIHL is irreversible, and prevention, even in the early stages, is of the utmost importance 3…”

BackgroundIndustrial noise is generally considered from the perspective of environmental health and safety, with requirements for reduced occupational noise exposure, strict standards for hearing protection, and public health awareness campaigns.Materials and methodsThis cross-sectional study aimed to identify the hearing threshold levels (HTLs) among steel industry workers exposed to hazardous noises in Samut Prakan Province, Thailand, and investigate the associations between hearing loss and age and length of employment in the industry. Audiometric data for 93 participants were collected at the Samut Prakan Provincial Hospital. Qualified technicians performed audiometric screening using an audiometer in a quiet environment. Tests were conducted after participants had completely rested for ≥14 hours after the last exposure to workplace noise.ResultsThe results showed that all participants had been employed in a work zone with a noise hazard for >1 year. Participants’ age ranged from 19 to 59 years and their work experience from 1 to 39 years. Average mean hearing thresholds in the right ear at 4, 6, and 8 kHz were 31.34, 29.62, and 25.64 dB, respectively. Mean hearing thresholds in the left ear at 4, 6, and 8 kHz were 40.15, 32.20, and 25.48 dB, respectively. Hearing loss related to work experience was greater than that attributable to age and work station. Duration of noise exposure ranged from 1 to 39 years, and more than half of the participants (60.2%) were exposed to hazardous noises from 6 to 25 years.ConclusionThese findings show that participants’ age and experience were significantly associated with hearing loss at all levels. HTLs among industrial workers should be regularly assessed. At the health policy level, these workers need to start being protected when they begin working.

“…The results of their studies show, that 235 employees were exposed to the noise for 16 to 20 years time. Among the employees with such job seniority 7 had medium hearing loss diagnosed in a right ear, while 8 in a left ear (25). A small number of diagnosed cases of hearing loss for women results from the fact, that the a/m occupational illnesses appears in sections and activities of PKD (Polish Activity Classification) where majority of the working staff are men.…”

INTRODUCTION. Among the population of adults, hearing loss related to occupational exposure to noise makes up ca 16%, which is the second etiological factor, after ageing, causing anomalies connected with hearing. According to statistical data, in Europe about 30 million of employees are exposed to the noise. In Poland the number equals to 187 500. AIM. The analysis of the structure of confirmed cases of occupational hearing loss between 2008-2017 in Poland and in Podkarpackie Voivodeship. METERIALS AND METHODS. Information related to Podkarpackie Voivodeship was obtained out of the cards verifying occupational illness, sent by National Sanitary District Inspectors from particular districts of Podkarpackie Voivodship to Podkarpacki National Provincial Sanitary Inspectorate. The data related to Poland within indicated period of time are obtained out of the studies entitled Occupational illnesses in Poland, published by Occupational Health Institute in Łódź. RESULTS. In Poland double permanent hearing loss is decreasing. In Podkarpackie Voivodship, during the analysed period of time, the incidence of recognition of occupational hearing loss was not high, a total of 74 cases, including 1 case when the illness concerned a woman. In most cases the occupational hearing loss caused by the noise in Poland and in Podkarpackie Voivodship was revealed in industrial processing. CONCLUSIONS. Most cases of occupational hearing loss in Poland was diagnosed with the men over 60 years old in Śląskie and Pomorskie Voivodeship, professionally linked to mining, heavy mechanical and metallurgical industry as well as means of transport. In Podkarpackie Voivodeship the increased number of diagnosed cases revealed in districts: stalowowolski, krośnieński, rzeszowski and przemyski (metallurgical and timber industry).
