Hearing Loss Definition
Definition
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
