2. Permissible exposure limit - Wikipedia

   en.wikipedia.org/wiki/Permissible_exposure_limit

   The current PEL for OSHA standards are based on a 5 decibel exchange rate. 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 ...

3. Occupational noise - Wikipedia

   en.wikipedia.org/wiki/Occupational_noise

   Each industry is different, as workers' tasks and equipment differ, but most regulations agree that noise becomes hazardous when it exceeds 85 decibels, for an 8-hour time exposure (typical work shift). This relationship between allotted noise level and exposure time is known as an exposure action value (EAV) or permissible exposure limit (PEL ...

4. Occupational hearing loss - Wikipedia

   en.wikipedia.org/wiki/Occupational_hearing_loss

   OHL caused by excessive exposure to noise is also known as noise-induced hearing loss (NIHL). Noise exposure combined with ototoxic chemical exposure can results in more damage to hearing. OHL caused by physical trauma may include foreign bodies in the ear, vibration, barotrauma, or head injury. OHL, as well as hearing loss in general, can ...

5. Threshold limit value - Wikipedia

   en.wikipedia.org/wiki/Threshold_limit_value

   However, many OSHA exposure limits are not considered by the industrial hygiene community to be sufficiently protective levels since the toxicological basis for most limits have not been updated since the 1960s. OSHA acknowledges this and recommends supplementing regulatory standards with alternative updated and stricter standards, "even when ...

6. Exposure action value - Wikipedia

   en.wikipedia.org/wiki/Exposure_action_value

   An Exposure Action Value (EAV) or Action Value (AV) is a limit set on occupational exposure to noise where, when those values are exceeded, employers must take steps to monitor the exposure levels. These levels are measured in decibels. The American Occupational Safety and Health Administration (OSHA) set the EAV to 85 dB

7. Noise-induced hearing loss - Wikipedia

   en.wikipedia.org/wiki/Noise-induced_hearing_loss

   In the United States, the Occupational Safety and Health Administration (OSHA) describes standards for occupational noise exposure in articles 1910.95 and 1926.52. OSHA states that an employer must implement hearing conservation programs for employees if the noise level of the workplace is equal to or above 85 dB(A) for an averaged eight-hour ...
