Exposure to extremely high noise levels may cause a permanent hearing loss.
Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time.
The U.S. Government’s Occupational and Health Administration (OSHA) has specified the following permissible noise level exposures:
Duration Per Day In Hours Sound Level dBA, Slow Response
90db - 8 hours max.
92db - 6 hours max
95db - 4 hours
97db - 3 hours
100db - 2 hours
102db - 1.5 hours max.
105db - 1 hour max.
110db - 30 minutes max.
115db - 15 minutes max.
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss.
Your hearing health is in your hands.
