Occupational hearing loss (OHL) is hearing loss that occurs as a result of occupational hazards, such as excessive noise and ototoxic chemicals. Noise is a common workplace hazard, and recognized as the risk factor for noise-induced hearing loss and tinnitus but it is not the only risk factor that can result in a work-related hearing loss.

Temporary hearing loss after loud noise exposure. If such exposure is long enough, this temporary threshold shift may become permanent. [13] Occupational noise, if experienced repeatedly, at high intensity, for an extended period of time, can cause noise-induced hearing loss (NIHL) [14] which is then classified as occupational hearing loss.
The Occupational Safety and Health Administration (OSHA) in the United States established the allowed exposure limit for occupational noise at 90 dB and is based on an 8-hour time-weighted average for an 8-hour workday. [16] For worker's safety, OSHA mandates hearing conservation programs when noise levels are higher than 85 decibels. [17]
Occupational hearing loss is the most common occupational illness in the manufacturing sector. [35] Workers in exceptionally high noise environments, such as musicians , [ 36 ] mine workers , [ 37 ] and even those involved with stock car racing , [ 38 ] are at a much higher risk of developing hearing loss, when compared to other workers (e.g ...
Hearing conservation programs [1] are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. . Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at ...
The same methodology was used to estimate the prevalence of hearing loss for noise-exposed U.S. workers within the Health Care and Social Assistance sector. [155] The prevalence of hearing loss in the Medical Laboratories subsector was 31% and in the Offices of All Other Miscellaneous Health Practitioners subsector was 24%.
Hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.
Personal noise dosimeters. A noise dosimeter (American English) or noise dosemeter (British English) is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the Occupational Safety and Health (OSHA) 29 CFR 1910.95 Occupational Noise Exposure Standard [1] or ...
