A cochlear implant is a device used to help individuals with severe hearing loss or deafness. It consists of an external microphone and speech processor that captures sounds, converting them into digital signals. These signals are transmitted to an implanted receiver-stimulator located under the skin behind the ear. The receiver-stimulator sends electrical impulses to an array of electrodes placed within the cochlea, the spiral-shaped structure in the inner ear. These electrodes stimulate the auditory nerve fibres, bypassing damaged hair cells. The brain interprets these signals as sound, enabling the recipient to perceive sound and regain a sense of hearing. To know more about how cochlear implant work read the full blog.
