What is the PEL for hearing protection?

90 dBA
OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker’s 8-hour time-weighted average (TWA) over a work day. For noise, OSHA’s permissible exposure limit (PEL) is an 8-hour TWA noise level of 90 dBA. 1 Time of exposure is reduced by half for each 5 dBA increase.

What is an acceptable dB noise level?

Decibel Level​ Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.

For example, a chain saw has a sound intensity of about 109 dB. Without proper hearing protection, running a chain saw for only 2 minutes can cause hearing loss! If you know someone with hearing loss, you know that conversation can be frustrating for both of you.
