Cochlear Implant (CI) is a surgical neural grit to provide a person with moderate to deep sensory hearing loss sensory sense of sound adjustment. CI goes beyond the normal acoustic hearing process to replace it with electrical signals that directly stimulate the auditory nerve. A person with an cochlear implant that receives intensive hearing training may learn to interpret these signals as sound and speech. However, one third of deaf children do not develop the language if they are only in ci and do not have input in sign language. Implant has two main components. The outer component is usually worn behind the ear, but can also be fitted to clothes, for example, in young children. This component, the audio processor, contains microphones, electronics including Digital Signal Processor Chips (DSP), battery, and coils that transmit a signal to the implant through the skin. The internal component, the actual implant, has coils to receive signals, electronics and a set of electrodes that are placed in the cochlea, which stimulate the cochlear nerve. The surgery is performed under general anesthesia. Surgical risks are minimal but can include tinnitus, bruising of the nerve and face and dizziness.
