Definition:

Acoustic trauma is injury to the hearing mechanisms within the inner ear, caused by excessively loud noise.

Alternative Names:
Injury - inner ear; Trauma - inner ear; Ear injury
Causes, incidence, and risk factors:

Acoustic trauma is a common cause of sensory hearing loss. Damage to the hearing mechanisms within the inner ear may result from an explosion near the ear, gunshots, or long exposure to loud noises (such as loud music or loud machinery).

Symptoms:
  • Hearing loss
    • Usually partial and involving high-pitched sounds
    • May be slowly progressive
  • Noises, ringing in the ear (tinnitus)
Signs and tests:

A good indicator of acoustic trauma is a hearing loss that follows exposure to noise. Audiometry may determine the extent of the hearing loss.
