Overview
Definition
Acoustic trauma is injury to the hearing mechanisms in the inner ear due to very loud noise.
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 be caused by:
- An explosion near the ear
- Gunshots
- Long-term exposure to loud noises (such as loud music or machinery)
Symptoms
- Hearing loss
- Usually partial and involving high-pitched sounds
- May slowly get worse
- Noises, ringing in the ear (tinnitus )
Signs and tests
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.
Treatment
The hearing loss may not be treatable. The goal of treatment is to protect the ear from further damage.
A hearing aid may help you communicate. You can learn coping skills, such as lip reading.
Support Groups
Expectations (prognosis)
Hearing loss may be permanent in the affected ear. Ear protection may prevent the hearing loss from getting worse.
Complications
Progressive hearing loss is the main complication of acoustic trauma.
Calling your health care provider
Call for an appointment with your health care provider if:
- You have symptoms of acoustic trauma
- Hearing loss occurs or gets worse
Prevention
- Wear protective ear plugs or earmuffs to protect against damage from loud equipment.
- Be aware of risks connected with activities such as shooting guns, using chain saws, or driving motorcycles or snowmobiles.
- Do not listen to loud music for long periods of time.
