Acoustic trauma is injury or damage to the hearing mechanisms located in the inner ear. This damage is due to very loud noise. Many people exposed to significant acoustic trauma will experience hearing loss, which can be temporary - sometimes called temporary threshold shift (TTS) - or in some cases permanent - sometimes called permanent threshold shift (PTS). If the acoustic trauma is significant enough patients can also sustain a ruptured eardrum (perforated tympanic membrane). The injury can be related to one very loud noise such as an explosion or by exposure over a long period of time to lower volume loud noise such as machinery.
Hearing loss can sometimes be irreversible but seeking medical attention immediately gives the patient the best chance of returning hearing to normal. As soon as you notice hearing loss, it is important to make an appointment with an ENT specialist and explain your situation. Your doctor will ask you what types of noises you've been exposed to during various times of your life to help make an accurate diagnosis. Your doctor may also use something called audiometry to detect signs of acoustic trauma. This test involves providing sounds of varying loudness and different tones to more carefully assess what you can and can't hear.
Hearing loss can be irreversible, it is important to seek medical attention. The hearing loss may need treatment or it may just resolve the issue on its own. Hearing loss can be irreversible. Even if the hearing loss is permanent, treatment can protect further loss of hearing.
