Our hearing is a valuable, sensitive sense organ. Hearing is a matter of course for most people. But noise-induced hearing loss rarely happens overnight. It builds up over time by any unprotected exposure to dangerous noise levels. This is whyappropriate hearing protection must be made available from 80 dB(A), as irreversible damage to the sensitive auditory cells is possible from this point.
Wearing hearing protection is mandatory in the workplace from 85 dB(A).
