When the role of the ear receptor performs electrode array, it looks like a very thin thread of platinum electrodes coming out of the receiver / stimulator. The word "implant" is not accidental - electrode array and receiver / stimulator implanted into the inner ear. But it does not need to be afraid.
Cochlear implants are miniature size (a few centimeters) and minimum weight (9-12 grams). Implants are safe for the human body. They are made of a biologically inert material. In particular, the cases of cochlear implants are often made of titanium. Health As speech processors, they can be hand-held or BTE. And in fact, and in another case, they do not cause inconvenience to the carrier.
In some cases, cochlear implantation is needed with deep deafness in both ears. In medical terms, this is expressed as follows: the average threshold of auditory perception at frequencies of 0.5, 1, and 2 kHz (range, responsible for the clarity and intelligibility of speech) is more than 95 dB (train noise).
In other words, one discerns only industrial noise and a voice-over in a creek.If hearing aids do not help to improve the perception of sounds for six months or more of use, if a person cannot distinguish between the sounds quieter than 55 decibels in the range of 2-4 kHz (noise boiling kettle feet from the ear), even when using a well-chosen hearing aids known as Tinnitus Miracle Review.
In the absence of the patient's psychological problems and severe chronic diseases, in some cases, it is impossible to conduct cochlear implantation at full or partial (but significant) obliteration of the cochlea.
