Cochlear implants are small electronic devices that can provide hearing even in the case of complete deafness. Normal hearing aids amplify the sound from the environment and give it back to the ear. In severe damage to the hairy cells in the inner ear, hearing is not possible no matter how much the volume is increased. In other words, normal hearing aids are not sufficient in severe or severe hearing loss. However, as the cochlear implant converts sound into electrical energy and transmits it to the auditory nerve, it provides hearing even in deafness situations after severe feathery cell loss.
The cochlear implant consists of two main parts, inner and outer. The outer part consists of a receiver (microphone) and a processor (processor) and is attached to the auricle and scalp. The outer part can be attached and removed just like hearing aids. The inner part consists of two parts (stimulator and electrode) placed in the inner ear and under the skin with a surgical operation.
- Microphone receives the voice, filters and processes.
- The processor incorporates the filtered sound into digital information and transmits it to the inner part.
- The inner part digitally transmitted sound is here converted into its eletric energy and then transmitted to the electrode placed in the inner ear.
- Electrodes, which distribute according to the frequency of the sound, by-pass the damaged hair cells, stimulate the auditory nerves electrically and ensure the transmission of the sound to the brain.
