Hearing Loss Definition & Overview


Hearing loss is a decreased ability to hear. There are two main categories of hearing loss:

Conductive hearing loss—due to something interfering with the sound passing to the inner ear.

Sensorineural hearing loss—due to damage to:

  • The major organ in the ear responsible for hearing (the cochlea).
  • The major nerve pathway (8th cranial nerve) and/or area of the brain responsible for hearing.
