2. Hearing protection fit-testing - Wikipedia

   en.wikipedia.org/wiki/Hearing_protection_fit-testing

   Hearing protector fit-testing is a method that measures the degree of noise reduction obtained from an individual wearing a particular hearing protection device (HPD) - for example, a noise canceling earplug or earmuff. Fit testing is necessary due to the fact that noise attenuation varies across individuals.

3. Hearing protection device - Wikipedia

   en.wikipedia.org/wiki/Hearing_protection_device

   Pre-molded earplugs have a preformed shape and a push-to-fit design. Formable earplugs are pliable and take the form of an individual's ear canal. Roll-down foam earplugs are one of the most commonly used earplugs, and are made from slow recovery foam which expands after it has been "rolled-down" and inserted in the ear canal, creating a ...

4. Auditory Hazard Assessment Algorithm for Humans - Wikipedia

   Through this method, the model was able to determine why a low level of energy at the ear canal entrance was much more hazardous than a higher level of energy at the ear canal entrance of an ear protected by ear muffs. The model discovered that the former featured a different pressure-time dependence than the latter that was able to more ...

5. Earplug - Wikipedia

   Using both ear muffs (whether passive or active) and earplugs simultaneously results in maximum protection, but the efficacy of such combined protection relative to preventing permanent ear damage is inconclusive, with evidence indicating that a combined noise reduction ratio (NRR) of only 36 dB (C-weighted) is the maximum possible using ear ...

   This includes but is not limited to personal noise reduction through the use of ear protection (i.e. earplugs and earmuffs), education, and hearing conservation programs. For the average person, there are three basic things that one can do to prevent NIHL: turn down the volume on devices, move away from the source of noise, and wear hearing ...
