Sensorineural Hearing Loss. Permanent hearing loss occurs when inner ear nerves become damaged and do not properly transmit their signals to the brain. Those who suffer from this condition may complain that people seem to mumble or that they hear, but do not understand, what is being said. The aging process is a very common cause of sensorineural hearing loss. As we get older, the inner ear nerves and sensory cells gradually die.
It may also occur in one ear or both ears. The most common reason for muffled hearing is conductive hearing loss that can be caused by a variety of factors or medical conditions including a build up of ear wax and ear infections. In most cases, however, it is treatable and does not lead to permanent hearing damage.
