2. 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.

3. 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 ...

4. 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

5. Noise control - Wikipedia

   en.wikipedia.org/wiki/Noise_control

   A variety of measures aim to reduce hazardous noise at its source. Programs such as Buy Quiet and the National Institute for Occupational Safety and Health (NIOSH) Prevention through design promote research and design of quiet equipment and renovation and replacement of older hazardous equipment with modern technologies. [10]

6. Noise dosimeter - Wikipedia

   en.wikipedia.org/wiki/Noise_dosimeter

   A noise or sound dose is the amount of sound a person is exposed to in a day. The dose is represented by a percentage. A noise dose of 100% means that a person has exceeded the permissible amount of noise. Any noise exposure after the 100% noise dose may damage hearing. The exchange rate is the rate at which exposure accumulates.

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 ...
