Safe Exposure Times

Safe exposure times

Being exposed to noise levels between 80 and 120 dB can cause insidious hearing damage—that is hearing impairment that occurs imperceptibly at the time but takes effect in a more noticeable way at a later date. The longer the duration of exposure, the more damage to hearing caused.

The equal energy principle follows that for every 3dB increase in sound intensity, there is a doubling in loudness perception. This in turn means that the effective safe exposure time halves, Please use the below chart as a point of reference.
