Sensorineural hearing losses occur when the "inner" ear or the actual hearing nerve itself becomes damaged.
Sensorineural hearing loss is often referred to as "nerve deafness." Nerve deafness is not really an accurate description because the damage most frequently occurs within the inner ear rather than the hearing nerve.
Scanning electron micrographs of the normal (a) and damaged (b) cochlear sensory epithelium. Also know as nerve-type hearing loss, this type of gradually-diminished hearing is commonly associated with the aging process. This type of hearing loss occurs when sound is inadequately conducted through the external or middle ear to the inner ear. Approximately 20 percent of patients with complaints of hearing problems suffer from this type of loss. The red blood cells circulate through the body carrying oxygen and nutrients to feed the cells. Diagnosis of this hearing loss type may involve a CT scan, MRI, and EEG (electroencephalogram) which measures electrical activity in the brain.

The white area represents the sounds that the person would not hear (softer then their thresholds) and the tan area indicates all of the sounds that the person would be able to hear (louder then their thresholds). About 90% of all people with hearing impairment are in this category, making it the most common type of hearing impairment.
In the normal cochlea, the stereocilia of a single row of inner hair cells (IHCs) and three rows of outer hair cells (OHCs) are present in an orderly array. Thus, "sensorineural" indicates the part of the ear that is malfunctioning and encompasses many different causes for the malfunction.
Additionally, anemia is characteried by low RBC (red blood cell) count, which also presents a reduced amount of oxygen to the body cells. It has a microphone for sound waves, an amplifier to increase sound, and a speaker that transmits to the ear. Couple these with a reduced circulation and you have a situation ripe for reduced oxygenation and circulation to the auditory system resulting in hearing loss. Then it travels to the middle ear, the inner ear to the cochlea, then to the brain where the sound is produced.


An audiologist will help you in choosing the right hearing aid for your needs.Cochlear implant is a surgically implanted hearing device that is comprised of the internal and external parts. However, most people with sensorineural loss find wearing hearing aids to be of significant benefit and some people with severe loss can benefit from a cochlear implant.
The internal part is inserted beneath the skin behind the ear in the temporal bone, that functions to stimulate the auditory nerve.
The external part is worn behind the ear, same as a behind the ear hearing aid, and transmits vibrations to the implanted piece. The sound is not like what is normally heard and will take some time to get accustomed to it.
