The World Health Organization had estimated approximately 278 million people internationally are impacted by moderate to profound hearing loss in both ears. Diagnostic medical records from the World Health Organization proposed that the incidence of hearing loss frequently increases due to the population ages and life expectancy rate improving. Additionally, according to healthyhearing 2012, the majority of type of hearing loss people experience are sensorineural hearing loss; hair cells in the inner ear or nerve pathways from the inner ear to the brain are severely damaged. Ranges of technology such as hearing aids continue to expand and assist victims of hearing loss, however; the technology scientists had produced and offered to the public in the past, could only amplify sound. The development of the cochlear implant had significantly expanded ever since an Australian otolaryngologist, Professor Graeme Clark and his team of three Melbourne health professionals- audiologist Professor Richard Dowell, surgeons Dr Robert Webb and Dr Brian Pyman had successfully formed a solution to effectively restore hearing by developing the first multi-channel hearing prosthesis and to prove his proposal; he performed the first implantable prosthetic “bionic ear” surgery on a human patient with the assistance of a medical technology organization, Nucleus in 1974. The success had established doctors to commercially perform cochlear implant in patients from 1982 to the present in Australia and other countries in the worldd.
International researchers applied an implanted device which presented wires internally and externally leading to the head of an individual. Clark hypothesized theoretically that the implanted device provides more opportunities...

According to the Co-operative Research Centre for Cochlear implant, the use of two microphones allows users to advance the perception of speech in environment, auditory nerve regeneration is necessary to enhance productivity, diminish surgery hazards and to fully develop a cochlear implant which resides under the skin completely in order to diminish the difficult use of the cochlear.
Ultimately, it is evident that Professor Graeme Clark had substantially changed the world for people with moderate to profound hearing loss despite the amount of risks. With the amount of limitations, the cochlear implant is referred to as premature technology which scientists are frequently improving. With technology gradually contributing, what will become the future development for the cochlear implant and how can their theoretical inquires become a reality?
Many times, people are left with an impaired brain for the rest of their lives and that damage can extend from being unable to control a limb to damaged eyesight to major memory loss. The purpose of implants is to aid the damaged portion of the brain to eradicate the symptoms that are associated with these serious brain disorders. Implants are inserted in the section of the brain that is impaired, whether it is the frontal lobe to help motor skills or in the occipital lobe to aid

Inspired by his deaf father he began to research the possibilities of an electronic implantable hearing device, a cochlear implant. His idea surfaced after reading an article by Blair Simmons. He was determined to give the deaf hearing as he had witnessed the frustration and isolation of those affected. His colleagues said a cochlear implant would be impossible, it was too complicated. His determination had paid off, and after a decade he had successfully invented the first cochlear implant. In 1978, Rod Saunders became the first recipient of Clark's implant.
Cochlear implants are electronic devices that sends signals directly to the auditory nerve. Cochlear implants consist of external parts which include the microphone, speech processor, and the transmitter. They also consist of internal parts that must be surgically placed under the skin including the receiver and electrical array. In order for the implant to work, the microphone
In support of Gallaudet University's, “Deaf President Now!” protest, Rev. Jesse L. Jackson once said “The problem is not that the deaf do not hear. The problem is that the hearing world does not listen.” (Lee) This concept been seen throughout Deaf history; Today it is especially noticeable now that technology has been developed to restore some hearing to many who are deaf. However these seemingly miraculous devices such as hearing aids and cochlear implants (CI) are a gilding for the real problem. CI’s in particular are thought to be a miracle cure for deafness, this misconception causes a great friction between Deaf and hearing culture. Deaf people should not be expected to get CI’s to “cure” their deafness for three primary reasons: CI’s promise more than they can deliver, they are an affront to Deaf culture, and ASL is a more effective way to insure development.
In 1985 the movie going community was enthralled with its newest hit movie titled Short Circuit. The movie portrayed a robot that due to accidental electrocution believed that it was alive. In the final scenes the robot know as Johnny five was seen removing one of its damaged robotic arms and replacing it with a new and identical arm. This idea of replacing one limb with another of equal function was unfortunately only movie fiction. This fiction however is quickly becoming a reality for countless thousands of people living with prosthetic limbs. In the October 1998 issue of Scientific American the story of Melissa Del Pozzo a thirteen year old girl living with a prosthetic limb gives an example of the hope many are living with. Her only dream is that she could one day tickle the ivories of her piano again. Her hope could soon be rewarded. With continued research, prosthesis's are making advancements that were once only dreams. These advancements are seeing the most change in the areas of dexterous movement, feeling, and comfort.
Hard of Hearing patients need something that will suit there financial goals in the long run, be less of a hassle to worry about and enhance their hearing all at the same time. We propose in creating a Battery-Less-Hearing Aid and believe that it is the best option to go because Hard of Hearing patients will never have to worry about recharging batteries or buying new ones all the time like you do with our current hearing aids that are available in today’s society. On top of that our patients would save money at the same time by never having to buy batteries and will still able to hear just like they would with a hearing aid that is battery operated.
Cochlear implants are amazing feats of biomedical engineering, and have helped many people regain the ability to hear. While there are some ethical dilemmas that go along with them, there is no denying just how amazing these implants really are. By understanding how the ear works, what causes it to stop working, and using science and engineering to fix that problem, there is now a way to give someone a sense they might have never been able to experience. It can be costly, but it could drastically change someone’s life. Some people may say for worse, but there will always be someone else to say it was for better. Overall, cochlear implants are an incredible invention and will continue to grow and only get better with technology.
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. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin. Usually, Deaf people are against the implant, because it would destroy the unique characteristic of themselves. Another point is that, the implant does not restore normal hearing. Instead, it can give a Deaf person only a representation of sounds in the environment and help him or her to understand the speech. Of course, the implant can change lives, but it is an individual choice. If a Deaf person does not want it, the decision must be respected. Audists feel that they have to force cochlear implants on Deaf people regardless of whenever they want it or not. Why would someone prefer to stay deaf? Simple: Members of the Deaf culture do not see themselves as disabled, and resent any discrimination or inference that they are disadvantaged. Their culture is wonderful and they are very proud to be part of
Cochlear implants are used for people who are completely Deaf, not being able to hear a single noise or hard of hearing individuals as well. Sound waves go into the ear, entering the ear canal, then hitting the eardrums in which vibrates. Vibration from the eardrum pass major parts in the ear, them being the bone called the Malleus, Incus, and Stapes. These three main parts in the ear amplify the pulse, and then are picked up by small hair-like calls in the cochlea. Moving as the vibration hits, evidence is then sent through the auditory nerve then to the brain, the brain processes the data and in which we describe as sound. A cochlear implant is a highly invasive procedure where the surgeon drills a small hole into the individual’s skull; opening the Malleus bone then a small hole is drilled into the cochlea where the electrodes are inserted. This procedure takes about 2-4 hours, and surgeons use general anesthesia. Having a magnet under the skin/skull for the receptor to hook to, and also have to shave out all little hairs around the cochlea, and spending $40,000 for this implant. Deaf children should not get the cochlear implant because it’s a dramatically change in ones life and affects the way they feel and see themselves.

The Cochlear Implant The cochlear implant is possibly one of the greatest inventions designed to benefit the deaf community. A cochlear implant is a device implanted internally behind a deaf persons ear with an external microphone, and is designed to provide artificial sounds to people who have nerve deafness in both ears and show no ability to understand speech through hearing aids. Since the development of the cochlear implant in the 1960’s, more than 10,000 people worldwide have been implanted with this device. Although this may seem like the perfect device to aid deafness, a lot of controversy still exists about the cochlear implant.
Parabolic Microphones and “Bionic Ears”- This technology allows a person to amplify sounds (i.e. talking, movement) from a long distance away. For example, a suspect’s conversation can be pinpointed and heard 50 meters away as if the sounds were coming from short distance.
