acoustic trauma

a sudden loss of hearing, partial or complete, caused by an extremely loud noise, a severe blow to the head, or other trauma. The greatest loss of hearing occurs at 4000 Hz. It may be temporary or permanent. Compare noise-induced hearing loss.

acoustic trauma

A type of sensory hearing loss due to injury to the hearing mechanisms in the inner ear, caused by very loud noise.
 
Clinical findings
Partial, generally slowly progressive hearing loss, especially for high-pitched sounds, accompanied by ringing or other noises.

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.
