CONSERVATION PROGRAM?

OSHA Permissible Noise Exposures

29CFR 1910.95 (a)

Protection against the effects of noise exposure shall be provided when the sound levels exceed those shown in Table G-16 when measured on the A scale of a standard sound level meter at slow response. When noise levels are determined by octave band analysis, the equivalent A-weighted sound level may be determined as follows:

TABLE G-16 - PERMISSIBLE NOISE EXPOSURES

 
Duration per day in hours Sound level dBA
8 90
6 92
4 95
3 97
2 100
1.5 102
1 105
.5 110
.25 or less 115
Footnote: When the daily noise exposure is composed of two or more periods of noise exposure of different levels, their combined effect should be considered, rather than the individual effect of each.

 

If you have Sound Levels of 85dBA or more, we calculate your time-weighted average (TWA) for an 8-hour period using noise dosimeter. If your TWA is greater than 85dBA, OSHA requires you to have a hearing conservation program in place. If your (TWA) is 90dBA or above, your exposed employees must wear hearing protection.
