A hearing loss occurs when there is a problem with one or more parts of the ear, the transmission of sound along the auditory nerve, and/or interruption/transmission of processing sound in the brain.
There are many causes of hearing problems ranging from something as simple as wax blocking the ear canal to serious medical problems requiring medical intervention. The only way to find out for sure is to have your hearing evaluated by an audiologist.
A sensorineural loss is the result of damage to the nerve fibers in the inner ear. It is commonly caused or exacerbated by the natural aging process, but can also be caused by noise exposure, strong medications, diabetes, stroke, and other circulatory diseases.
Hearing aids are the best solution to a sensorineural hearing loss.
