2. 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

3. Permissible exposure limit - Wikipedia

   en.wikipedia.org/wiki/Permissible_exposure_limit

   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]

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. Occupational noise - Wikipedia

   en.wikipedia.org/wiki/Occupational_noise

   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.

6. Hearing protection device - Wikipedia

   en.wikipedia.org/wiki/Hearing_protection_device

   NIOSH base their recommendations for use of hearing protection by a calculation called time-weighted average (TWA). A time-weighted average is the average noise level a worker is exposed to over a period of time. NIOSH recommends that OSHA use an 85 dBA time-weighted average during an 8-hour period as their exposure limit. [1]

7. Hearing conservation program - Wikipedia

   en.wikipedia.org/wiki/Hearing_conservation_program

   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 ...
