The inner ear contains the cochlea‚ filled with fluid essential to sound transmission. Stapes movement on the oval window causes the liquid to vibrate and travel up the spiraling structure‚ passing through the upper (scala vestibuli) and lower portion (scala tympani) to the round window

Elena Chwat Mr. Amelio English 10H The Deaf Culture and its View on Cochlear Implants In the United States alone‚ there are over two million deaf people‚ (“Deaf Population…”) which is only a small fraction of hearing people in the US. Being a minority‚ the deaf culture is often misunderstood and discriminated against. Deaf people view themselves as a community – they have a language‚ a culture‚ and a bond with each other.

“Deafness” Deafness is the inability or lowered ability to hear. It can affect one or both ears‚ and the onset may be gradual or sudden. The causes are varied‚ and there are many forms of treatment and devices available to remove or lighten the symptoms. Doctors and researchers have studied the ear to find out exactly how it works and how it affects deafness. Sound is caused by vibrations occurring in waves within the atmosphere. For a normal ear‚ these sounds waves travel along the outer ear and

Abstract Bionics is a field‚ which combines both electronics and biology. In simple terms‚ when we think about bionics‚ it is generally more about prosthetic arms or leg enhancement worn outside the body and‚ to some extend‚ even implanted sensor devices inside the body‚ which are essentially enhanced to carry out certain routine tasks. These are essentially life systems that are powered by motors/actuators and sensory arrays. These send neural signals from affected part of the body to the brain

The biggest controversy of the deaf community has been the topic of a cochlear implant. The debate is centered around the expense‚ risk and idea of the implants causing deaf people to distance themselves from the deaf community rather than emerging themselves. This is due to the cochlear implants ability to provide a sense of sound to the deaf individual. It is only used when a hearing aid is not strong enough to provide adequate function. The cochlear implant involves a lot of time to consider the

That condition typically involves damage to tiny hair cells in a part of your inner ear called the cochlea. These hair cells usually pick up the vibrations of sounds and send them to the brain through the auditory nerve. When they’re damaged‚ sound can’t reach that nerve. A cochlear implant skips the damaged hair cells and sends signals to the auditory

Learning and the Hearing Impaired Students who are hearing impaired should be provided with special needs in a way that addresses the student ’s individual differences and needs. Advances in research on effective instructional practices can provide guidance for general education teachers and special education teachers who have little or no training in methods for students with hearing loss.

The other part of Usher Syndrome‚ the hearing loss‚ is due to a genetic mutation affecting nerve cells in the cochlea‚ a sound transmitting structure in the inner ear. The same genetic effect also adversely affects photoreceptor cells in the retina leading to vision loss. Usher Syndrome is a heterogeneous disease meaning it comes in several different types‚ in
