OVERVIEW

Deafness, or hearing impairment, is a condition in which hearing is completely or partially impaired.

There are three main types of hearing loss:

  • Conductive hearing loss (when sounds are unable to move from the outer ear to the inner ear)
  • Sensorineural hearing loss (when the hair cells in the cochlea or auditory nerve are damaged)
  • Mixed hearing loss (caused by both conductive and sensorineural hearing loss)
