How many decibels is harmful to your hearing?

What is the normal range of noise in the human ear?
The human ear as a dyamic range from 0dB (threshold) to 120-130 dB. This is true for the middle frequency range (1-2 kHz). For lower or higher frequencies, the dynamic is narrowed. However, as shown on this graph, all sounds above 90 dB are damaging the inner ear and even doing irreversible damage above 120 dB. (see ” Noise: watch out !
