Acoustic trauma

[2] Acute acoustic trauma can be treated by combining hyperbaric oxygen therapy (HBO) with corticosteroids.

Acute noise exposure causes inflammation and lower oxygen supply in the inner ear.

[medical citation needed] Many cases have included a period of reduced hearing after exposure to loud sounds.

[5] Acoustic trauma occurs when a continuous transient sounds transfers enough energy to a cochlea to result in necrosis of the outer hair cells (OHC), inner hair cells (IHC), and cause glutamate excitotoxicity of first-order afferent neurons of the spiral ganglion (cochlear synaptopathy).

[8] Once exposure to damaging noise levels is discontinued, further significant progression of hearing loss stops.

[9] Below are possible preventive measures and treatment methods that could help in cases of acoustic trauma Each episode of acoustic trauma results in permanent damage within the inner ear, even though the majority of patients, the symptoms will disappear and an audiogram will show normal hearing within a few hours to a few days.

[10] There is no specific study done on Life Expectancy or statistical information for the prognosis of acoustic trauma.

Acoustic trauma is quite common during military service and during hunting activities, where it is mainly associated with gun sports and particularly accidental shots.

[12] Of teenagers, 20-50 percent experience exposure to noise levels high enough to cause acute acoustic trauma.

The oval perforation in this left tympanic membrane was the result of a slap on the ear four days previously. The sudden increased air pressure in the external auditory canal produced this traumatic blast perforation.
