Hearing loss

Similar term(s): hearing impairment.

Hearing loss is a reduced ability to hear sounds in comparison to normal hearing. Hearing loss ranges from slight to profound.

Hearing loss can be caused by aging (age-induced hearing loss), illness or disease, by excessive exposure to high noise levels (noise-induced hearing loss) or by excessive exposure to loud sounds (sound-induced hearing loss).
