It is due to very loud noise. Causes Acoustic trauma is a common cause of sensory hearing loss.

The hearing loss may slowly get worse. Noises, ringing in the ear (tinnitus).TinnitusTinnitus is the medical term for "hearing" noises in your ears.

Possible Complications Progressive hearing loss is the main complication of acoustic trauma.Tinnitus (ear ringing) can also occur. When to Contact a Medical Professional Contact your provider if: You have symptoms of acoustic trauma Hearing loss occurs or gets worse Prevention Take the following steps to help prevent hearing loss:Wear protective ear plugs or earmuffs to prevent hearing damage from loud equipment.

These impulses then travel to the brain where they are interpreted by the brain as sound. The hearing mechanisms within the inner ear, can be easily damaged by excessively loud noise causing sensory hearing loss.Sound wave transmissionillustrationSound wave transmission - illustration When sounds waves reach the ear, they are translated into nerve impulses.
