2. | ![]() OSHA’s permissible exposure limit (PEL) for noise exposure is 90 dBA for an 8-hour TWA and the standard uses a 5 dBA exchange rate. This means that when the noise level is increased by 5 dBA, the amount of time a person can be exposed is cut in half. For example, a person who is exposed to noise levels of 95 dBA (5 dBA above the OSHA PEL of 90 dBA) can be exposed for only 4 hours in order to be within the daily OSHA PEL. See Table D-2 for permissible Noise Exposure.
