What is the primary function of cochlear implants?

The primary function of cochlear implants is to directly stimulate the auditory pathway. Unlike hearing aids, which amplify sound for individuals with residual hearing, cochlear implants bypass damaged structures in the inner ear and stimulate the auditory nerve directly. This is particularly beneficial for individuals with profound hearing loss or complete deafness who do not gain sufficient benefit from traditional amplification devices.

Cochlear implants consist of an external component that captures sound and converts it into digital signals, which are then sent to an internal component surgically implanted in the cochlea. This internal component stimulates the auditory nerve endings, allowing the brain to perceive sound. Thus, the role of cochlear implants is to restore a sense of hearing by turning sound waves into electrical signals that the auditory system can process.

In contrast, assisting with amplification is the primary role of hearing aids, while compensating for ear wax blockage and repositioning the ear structure do not relate to the functions of cochlear implants.
