There are two main types of hearing loss.
Sensorineural hearing loss is caused by damage to the hair cells inside the inner ear, or damage to the hearing nerve, or both. This type of hearing loss is permanent but can often be treated by hearing aids. Age-related damage to the inner ear is the single biggest cause of hearing loss.
Conductive hearing loss happens when a blockage, such as ear wax, stops sound passing from the outer ear to the inner ear. This can be temporary or permanent.
It’s possible to have both types of hearing loss.
