Cochlear Implant

A cochlear implant is an electronic device, which is surgically implanted in the inner ear to directly stimulate the hearing nerve. The cochlear implant consists of:

Sound Processor: It helps in capturing sounds and converting them into digital signals. It further sends the signals directly to the internal device.

Coil/Cable Unit: It links the sound processor with the internal implant inside the skin. It helps in transmitting electrical impulses to enable hearing.

Internal Device: It is the main element of the cochlear implant, consisting of the electrode array. It is implanted surgically into the cochlea of the ear. The electrodes further stimulate the patient’s hearing nerve and enable the brain to perceive the signals on hearing sounds.

How Does a Cochlear Device Work?

In normal ears, the sound is usually transmitted via air, enabling the eardrum and the middle ear bones (ossicles) to vibrate. Due to this, a vibratory wave is passed into the cochlea (or the inner ear). These vibratory waves then convert into electrical signals that are sent along the auditory nerve to the person’s brain.

However, a hearing-impaired person won’t have a functioning inner ear. With the help of the cochlear implant, ENTs try to replace the function of the cochlea by converting mechanical energy into electrical energy that’s further used for stimulating the cochlear nerve to send the “sound” signals to the person’s brain.

But even with a cochlear implant, the patient still has the hearing loss. As the cochlear implant allows the patient only to hear the sounds – NOT understand them. It is only useful in a quiet environment – NOT Noisy Situations!
