Here's an example: OSHA allows 8 hours of exposure to 90 dBA but only 2 hours of exposure to 100 dBA sound levels. NIOSH would recommend limiting the 8 hour exposure to less than 85 dBA. At 100 dBA, NIOSH recommends less than 15 minutes of exposure per day.

With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. Occupational standards specify a maximum allowable daily noise dose, expressed in percentages. For example, a person exposed to 85 dBA per NIOSH or 90 dBA per OSHA over an 8-hour work shift, will reach 100% of their daily noise dose.

2. Assure exposure of: 100 dBA for 2 hours, 90 dBA for 6 hours. D = 2/2 + 6/8 = 1.75. Engineering or administrative controls are necessary to reduce noise dose to unity. 3. Assume exposure of: 100 dBA for 1 hour 90 dBA for 4 hours 85 dBA for 3 hours
