Sensorineural hearing loss is a type of hearing impairment that occurs when a hearing problem is associated with a failure to transmit neural signals from the cochlea in the inner ear to the brain. It is recognized as the most common form of hearing loss.

Sensorineural Hearing Loss

A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing.

-  A microphone, which picks up sound from the environment.
-  A speech processor, which selects and arranges sounds picked up by the microphone.
-  A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
-  An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve.

Cochlear Implants

Sensorineural hearing loss can result from various factors, including aging, head or acoustic trauma, diseases such as measles or mumps, medications, environmental noise exposure, tumors, and toxins from certain solvents and metals.

Causes of Sensorineural Hearing Loss

Ménière's disease is a condition that results in a degeneration of inner ear structures, leading to sensorineural hearing loss. Symptoms of this disease include hearing loss, tinnitus (a constant ringing or buzzing), vertigo (a sense of spinning), and an increase in pressure within the inner ear.
