2019-01-25 2012-12-31 Due to the impact of continued exposure to loud noise over time, usually the younger we are, the better we hear. The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz.Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.

Decibel Scale. Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful.

140 extremely damaging to hearing no matter how short the time exposure. 140 blast wind = u = (particle velocity) is 0.49 meters per 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.
