The OSHA Permissible Exposure Limit (PEL) for Noise is 90 dBA taken as an average over an 8-hour working day. If large portions of the work day do not involve exposure to noise, the averaging results in permitting louder noise for shorter exposure times.
PEL .... Time Exposed during one day
90 ...... 8 hours
95 ...... 4 hours
100 .... 2 hours
105 .... 1 hour
110 ..... 30 minutes
115 ..... 15 minutes
Unprotected exposures over 115 dBA not permitted. All the above presumes no exposure over 90 dBA during the rest of the work shift.
In addition, if the daily average noise exposure exceed 85 dBA, each person likely to be so exposed must be part of a hearing conservation program involving training, periodic hearing testing, and availability of hearing protectors. A similar table as above applies, but beginning at 85 dBA for 8 hours and going to 80 dBA for 4 hours, etc. These levels presume no exposure over 80 dBA during the rest of the work shift.
(Note the no exposure presumption is different for Hearing conservation than for the basic PEL)

What is LA90?
LA90 is a standard way of specifying background noise over a given time. It is the noise level that is exceeded for 90% of the time being considered. E.g. 25dBA LA90 (10min) means that for a given 15 min period noise levels would be above 25dBA for 90% of the time. It can also be used as a Noise Management Level for construction purposes where works are being conducted around residential areas. See the related link for more information.
