Exposure to harmful sounds causes damage to the hair cells as well as the auditory nerve. Impulse sound can result in immediate hearing loss that may be permanent. This kind of hearing loss may be accompanied by tinnitus - a ringing, buzzing, or roaring in the ears or head. Hearing loss and tinnitus may be experienced in one or both ears, and tinnitus may continue constantly or occasionally throughout a lifetime.

Continuous exposure to loud noise can also damage the structure of hair cells, resulting in hearing loss and tinnitus, although the process occurs more gradually than for impulse noise.

The Ear Institute, with branches across the country, offers advice and hearing tests.
