Acoustic trauma is injury to the hearing mechanisms in the inner ear due to very loud noise.
Acoustic trauma is a common cause of sensory hearing loss. Damage to the hearing mechanisms within the inner ear may be caused by:
The health care provider will usually suspect acoustic trauma if hearing loss occurs after noise exposure. Audiometry may determine how much hearing has been lost.
The hearing loss may not be treatable. The goal of treatment is to protect the ear from further damage. Eardrum repair may be needed.
A hearing aid may help you communicate. You can learn coping skills, such as lip reading.
Hearing loss may be permanent in the affected ear. Ear protection may prevent the hearing loss from getting worse.
Progressive hearing loss is the main complication of acoustic trauma.
Tinnitus (ear ringing) can also occur.
