This implant consists of two major components: an external component known as the sound processor and an internal component known as the implant. The sound processor receives sound waves and processes them into detailed digital information. The implant converts the digital information into electrical information, which is sent to the auditory nerve from an electrode array placed inside the cochlea. The auditory nerve sends impulses to the brain, where these sound waves are processed and interpreted.

Change blindness: failing to notice ... * Preview Question 12: What are the common causes of hearing loss, and why does controversy surround cochlear implants? Title:
Hearing loss problem is a common problem for people as age increases hearing loss problem started but now a days this is a common problem for kids also. There are 2 types of hearing loss are sensorineural and conductive. 1.Sensorineural hearing loss is the most common diseases and it damage to the inner sensing organ cochlea or to the nerves it is directly connect with the inner ear to the brain. Most of the time, Sensorineural can’t be corrected, although hearing aids and cochlear implants can help.
Accessing the inner ear can be challenging due to its location and because direct access to the cochlea can result in hearing loss and/or balance disorders. Therefore it’s easier to access via the tympanic membrane or through the middle ear itself.Using the middle ear as a route to the inner ear, however, still allows for a plethora of approaches to the inner ear itself.
