There are three types of hearing loss:
Sensorineural hearing loss—This type of hearing loss happens when nerves in the ear that register sounds and send signals to the brain are damaged.
Conductive hearing loss—This type of hearing loss happens when sounds cannot get to the inner ear because of problems in the middle or outer ear. Conductive hearing loss can happen if you have too much wax in your ear, and sounds are being muffled. It can also happen if you have an ear infection and parts of your ear are swollen or filled with fluid.
Mixed hearing loss—Mixed hearing loss happens when both types of hearing loss occur at the same time.
