Hearing loss is not fatal; it 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.
