acoustic trauma

The often damaging effect of loud noise on the inner ear. The degree of damage is related to the intensity multiplied by the time. A nearby explosion may cause as much damage as years of exposure to noise of lower amplitude. The hair cells in the ORGAN OF CORTI are injured by excessive movement and the higher pitched sounds are the first to be lost.
