It is important to differentiate between noise level and time-weighted average noise exposure. While noise levels describe the intensity of sounds at a given point in time, the NIOSH and EPA exposure limits are set as time-weighted average exposures over periods of time.

Noise - Occupational Exposure Limits in Canada : OSH Answers

Noise regulations in several jurisdictions treat impulse noise separately from continuous noise. A common approach is to limit the number of impulses at a given peak pressure over a workday. The exact figures vary slightly, but generally the regulations in which the exchange rate is 5 dB permit 10,000 impulses at a peak pressure level of 120 dB ...Noise Pollution and Its Control in MiningSound Level: Noise known as a major health hazard is spot specific in case of underground mining where the operators are exposed to continuous background noise while high level short duration noise peaks are common in case of surface mining.
