A majority of cases of hearing loss is due to sensorineural hearing loss. Sensorineural hearing loss is hearing loss that is caused by damage or deficit of the auditory nerve, also called the eighth nerve, or the cochlea. Sensorineural deafness is sometimes called nerve deafness since it is often caused by a malfunction of the auditory nerve. This is in contrast to conductive hearing loss which is caused by a blockage of sound reaching the inner ear. In sensorineural hearing loss, the sound travels freely to the inner ear where the cochlea or auditory nerve fails to transmit the sound to the brain.
Sensorineural hearing loss is considered permanent hearing loss that cannot be surgically corrected. The hearing loss can range from mild loss of volume of sound to complete deafness. Sensorineural hearing loss can also affect the clarity of sound and the ability to understand people speaking. The hearing loss can start suddenly or gradually. Other symptoms of nerve deafness include dizziness or tinnitus which is a ringing in the ears.
The most common causes of sensorineural hearing loss are injuries during birth, diseases, genetic conditions, and drugs. Head trauma, aging, illness, tumors, and injury can be causes of nerve deafness. Noise exposure can also cause sensorineural hearing loss. Damage to the blood vessels to the cochlea can cause nerve deafness. This blood vessel damage can be caused by diabetes or degenerative cardiovascular disease. If the cause is unknown, the condition is called idiopathic sensorineural hearing loss.
When diagnosing hearing loss, the physician is likely to perform an ear exam and ask questions about the development of the hearing loss and conduct one or more hearing tests. People with cochlear impairment fail Otoacoutic Emissions Testing (OAE) which records sounds that the ear produces. Other testing can detect deficits of the eighth nerve.
Depending on the type and degree of hearing loss, a hearing aid may help someone with this type of hearing loss. Cochlear implants are sometimes used as a nerve deafness treatment. This treatment for sensorineural hearing loss works by implanting an electronic device that stimulates the auditory nerve from the cochlea.

Good Day
I purchased a hearing aid for my mother back in december which had to be returned because the dye in the aid caused a minor ear infection. We exchanged it for the model 2100 in late february but my mother went into intensive care and we almost lost her so I called wanting to cancel the order but the customer rep Ms.Victoria Zambrano impressed upon me to hold the order until my mother was well enough so she could help her with her hearing problem.
We picked the aid late February early march and mom tried in vain to become comfortable with the aid but the steel implants in her neck created so much interferences in her head she could not stand the pain. I called back to cancel the order because it became evident that my mother just could not stand the pain and we are being ignored now that we cannot use the technology.
It has become extremely frustrating to be ignored when you call time again to leave message and no representative from the kings plaza office wants to help … We feel really used and we are sitting here caring for all the health issues my aging mother has to endure trying to create a situation where everybody wins. Miracle ear gets to keep 10% of the fee paid for the aid $2600.00 ,Someone else who really can use it can get helped and we get the rest of the deposit back to get mom something to make her smile these days which we have not seen much. PLEASE help us with this issue … I really don,t see the problem when everybody wins. I came to Miracle ear as a customer and put my trust in your hands . Thank you for listening .

Thanks for sharing, there has been many breakthroughs for hearing impaired persons. Skype and Google Talk are providing VOIP from which deaf people can make video call and communicate with their friends and loved ones. According to a variety of reports it now looks as if video calls make their way into the mainstream. The iPhone 4 and Facetime can give another boost to it.

I failed to read the contract closely. Never getting what I wanted despite the cost, I returned to my audiologist, and he continued attempting adjustments, none of which have helped. Then I realized that with all the fiddling around I had passed the 30-day deadline for refundable return. Out of luck!

Wow they really have everything! Costco is a great company, but like many nationwide businesses it can have some weak spots.

I think their service stinks. I was sick and they kept me waiting and waiting and waiting while the man I was
supposed to see went to the bathroom and was simply walking around and doing nothing. When it reached
15 minutes past my appointment time, I walked out. They called later and apologized, but I think it was
deliberate because I was sick. I had cancelled several appointments because of illness, but that time I
went in anyway. I told them I would call when I was better, but they kept calling me and then when I went in
even though I should have stayed home, they insulted and ignored me.

Really, This is the wonderful information. I think, The Phonak company has categorized their hearing aids as standard, advanced, or premium. In addition to the variety of options, Phonak provides hearing aid accessories that may provide even more customization to meet the client’s specific needs.

This is the great blog. I think, Hearing aid only two types. One is the digital hearing aid, And another is analog. These are the most popular hearing aid. The middle ear implant (MEI) moves the bones of the middle ear as they would for someone without a hearing impairment. The bone-anchored hearing aid (BAHA) delivers sound from its attachment to the skull directly to the inner ear by bypassing the middle ear.

so far i have been through 3 sets of hearing aids. the first pair were the widex clear 220, next the phonak cassia, then lastly the phonak solana. the phonak ais sound muffled, and i find that both aids turn off sporaticly. i bought the phonak because i listened to other people. the best hearing aid i had was the widex clear 220. i should try for the widex clear 330 instead of the phonak solana. what do you think.

Phonak hearing aids are available in many shapes and colors, one of the most discrete ones being the Completely-in-the-Canal model, which can barely be seen by others, but which, unfortunately, doesn’t feature wireless connectivity. Nevertheless, if you really need the wireless functionality, you can choose the Phonak In-the-Canal model which is also very discrete hearing aid.
