The National Institute for Occupational Safety - NIOSH - Recommended Exposure Limit - REL - for occupational noise exposure is

85 decibels, A-weighted, as an 8-hr Time-Weighted Average -TWA - (85 dBA as an 8-hr TWA)

Note! Exposures at and above this level are considered hazardous.

Exposure to continuous, varying, intermittent, or impulsive noise shall never exceed 140 dBA.
