When Sound Hurts

NIHL is related to both noise intensity and the duration of exposure. The relationship between sound levels and exposure limits is illustrated below. The Table (below) shows how quickly sound tolerance limits decrease with small increases in sound intensity levels. Recall, this is because an increase of 10 dB corresponds to a 10 fold increase in sound intensity. Simply put, the louder the sound, the shorter the time before damage occurs..and the relationship isn’t linear! Here’s an important take-away: there are no treatments…not medicine, not surgery, not hearing aids…that can restore your natural hearing once it is damaged by noise. …
