Bionic Ear The bionic head (cochl pinnule implant) is an artificial listening device designed to help hearing impaired and deep deaf people. separate of the bionic ear are enroll into the skull other move are faint-hearted on the out post of the body, the interior(a) par t is called the head set. The headset consists of a 22-channel stimulator that is held in a titanium capsule with platinum electrodes which is inserted into the shell-like structure in the inside(a) ear known as the cochlea. A ball electrode is implanted to a lower place a muscle near the ear. The speech processor is outwardly worn, it can be worn dirty dog an ear or held in a pocket. The coil is held in plaza against the tegument by a magnet and the mike is worn behind the ear. Speech and other sounds are picked up by the microphone and are sent to the speech processor. The speech processor changes sounds into voltaic signals that are sent through a cable to the infection coil. The coil se nds the signals through the skin to the implant which transforms the signal to galvanic pulses. The pulses pass from the electrode array and stimulate hearing nerve fibres at bottom the cochlea.
It is not possible to make the sounds heard by the bionic ear completely natural, and this is because in the implant their are still 22 electrodes that are replacing the function of thousands of copper cells in a normal hearing ear. The materials used in the bionic ear are platinum and titanium, below is both(prenominal) nurture on the two elements.
