Noise induced hearing loss can occur over long exposure to loud noise or a one time exposure to a loud sound such as an explosion, this happens when damage occurs to the minute hair cells in the cochlear. These hair cells send different sound frequencies to the auditory nerve which enables us to identify them as different sounds, when these become damaged then the hearing is affected.
If you have excellent hearing then you will be able to hear a range of different sounds from 20Hz to 20,000 Hz but over a period of time the hair cells can become damaged and if the damage is due to loud noise it is usually the high frequency area of the cochlea which becomes affected.
