Acoustic trauma is a common cause of sensory hearing loss. Damage to the hearing mechanisms within the inner ear may be caused by:
Exams and Tests
The health care provider will most often suspect acoustic trauma if hearing loss occurs after noise exposure. A physical exam will determine if the eardrum is damaged. 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 also learn coping skills, such as lip reading.
Hearing loss may be permanent in the affected ear. Wearing ear protection when around sources of loud sounds may prevent the hearing loss from getting worse.
Progressive hearing loss is the main complication of acoustic trauma.
Tinnitus (ear ringing) can also occur.
