Overall, audiometric records show that about 33% of working-age adults with a history of occupational noise exposure have evidence of noise-induced hearing damage, and 16% of noise-exposed workers have material hearing impairment. [9] In the service sector the prevalence of hearing loss was 17% compared to 16% for all industries combined. [10]
Occupational noise exposure is the main risk factor for work-related hearing loss. One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.
Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage.
Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [5] The National Institute for Occupational Safety and Health (NIOSH) recognizes that the majority of hearing loss is not due to age, but due to noise exposure. By correcting for age in assessing ...
An example of this would be in dogs, and the noise exposure levels occurring within kennels. Dogs experience this noise exposure whether it be a long stay at an animal shelter, or a weekend stay at a boarding facility. Organizations like NIOSH and OSHA have different regulations when it comes to the noise exposure levels in industrial workers ...
Noise presents a fairly common workplace hazard: occupational hearing loss is the most common work-related injury in the United States, with 22 million workers exposed to hazardous noise levels at work and an estimated $242 million spent annually on worker's compensation for hearing loss disability.

Many countries require several interventions to control risks from exposures to loud noise in the workplace. For example, US Occupational Safety and Health Administration requires hearing conservation programs which include the provision of hearing protection devices. This does not mean that OSHA considers HPDs to be effective.
OSHA's PEL for noise exposure is 90 decibels (dBA) for an 8-hour TWA. Levels of 90-140 dBA are included in the noise dose. [4] PEL can also be expressed as 100 percent “dose” for noise exposure. When the noise exposure increases by 5 dB, the exposure time is cut in half. [5] According to OSHA, a 95dBA TWA would be a 200 percent dose. [6]
