2. Sound exposure - Wikipedia

   en.wikipedia.org/wiki/Sound_exposure

   Sound exposure level (SEL) is a logarithmic measure of the sound exposure of a sound relative to a reference value. Sound exposure level, denoted L E and measured in dB , is defined by [ 1 ]

3. Hearing protection fit-testing - Wikipedia

   en.wikipedia.org/wiki/Hearing_protection_fit-testing

   The outcome measure generated by hearing protector fit-test systems varies from a simple pass/fail to a quantitative personal attenuation rating (PAR). and can be interpreted differently to determine the effectiveness of hearing protection or calculate total noise exposure. [22]

4. Auditory Hazard Assessment Algorithm for Humans - Wikipedia

   en.wikipedia.org/wiki/Auditory_Hazard_Assessment...

   Noise-induced hearing loss (NIHL) typically occurs when the auditory system experiences an elevation of hearing thresholds due to exposure to high-level noise, a phenomenon known as a temporary threshold shift (TTS), and does not return to normal threshold levels. [6] The damage to the auditory system can vary depending on the type of noise ...

   Acoustic trauma can occur from a single, loud noise exposure or loud noise over a period of time. One sign of acoustic trauma is ringing in the ears and muffled hearing after a loud sound exposure.

7. 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]
