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?
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.

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
Cochlear Implants are frequently thought of as an end all solution to hearing loss, a cure for deafness. However there are a couple things wrong with this line of thinking: First CI’s are not a perfect replacement for fully functioning ears. Second, they will only work for a few deaf people.
The skin technologies that have recently been created are astonishing. The remarkable breakthrough has made a huge advance in technology happen. Muscle and nerve control operation is when electrodes are permanently implanted into the nerves and muscles allowing the amputees limb to have total direct control. With this new muscle to nerve action
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.

Individuals who are deaf or are hearing impaired are faced with many problems in today’s world. There are so many tasks and activities that are done today that deaf or hearing impaired people may have difficulty doing because of there handicap. There handicap used to stop them or inhibit them from doing something that they are interested in or there friends and neighbors would do. However in today there are new and different technologies, that help the deaf and hearing impaired in the activities in which they want to participate in which is hard for them to take part in because of there handicap. Technology is used to help with everyday tasks in the lives of deaf and hearing impaired individuals. With out this new technology which is being invented everyday, deaf and hearing impaired people may be considered to have a handicap which prevents them from certain activities, but this is not the case anymore, now these people just have different obstacles which through the use of technology they are learning to over come. They can do anything that regular normal range of hearing individuals can do, due to the new technology being invented everyday.
In my life, I've had a major setback that has changed how I live life day to day. When I was five, I was diagnosed with permanent hearing loss. I have hearing loss in both ears, mostly in higher frequencies, but I still have some hearing loss in the lower ones too. Since I was 5, it has only gotten worse, just in the past year there has been drastic changes in the frequencies that I can't hear. Hearing loss affects me day to day, for example if anyone whispers something to me, nine of ten times I can't hear what they are saying. My academics also get affected because sometimes I can't hear what we have for homework over all of the background noise of people packing up, so sometimes I just don't do homework because I never heard it in the first place. Not doing homework because I can't hear it affects my grades as I will get zeros for not doing it.
Hearing loss is often overlooked because our hearing is an invisible sense that is always expected to be in action. Yet, there are people everywhere that suffer from the effects of hearing loss. It is important to study and understand all aspects of the many different types and reasons for hearing loss. The loss of this particular sense can be socially debilitating. It can affect the communication skills of the person, not only in receiving information, but also in giving the correct response. This paper focuses primarily on hearing loss in the elderly. One thing that affects older individuals' communication is the difficulty they often experience when recognizing time compressed speech. Time compressed speech involves fast and unclear conversational speech. Many older listeners can detect the sound of the speech being spoken, but it is still unclear (Pichora-Fuller, 2000). In order to help with diagnosis and rehabilitation, we need to understand why speech is unclear even when it is audible. The answer to that question would also help in the development of hearing aids and other communication devices. Also, as we come to understand the reasoning behind this question and as we become more knowledgeable about what older adults can and cannot hear, we can better accommodate them in our day to day interactions.

...ur brain. They have already made huge improvements in this area of prosthetics by creating some that can be controlled by the brain, but they aren’t used over a mass amount of people. In order to reach these goals we have to supply funding to the prosthetic and orthotic companies. Some are still using techniques that have been around for decades. In order for the field of prosthetics to advance in this world steps have to be taken in educating people in the new technology. I personally hope that in my lifetime I will be able to see prosthetics grow to what it can be in helping everyone, not just the people who can afford. This also means that we need to not just make prosthetics that work, but that have the patients comfort in mind. Overall prosthetics should be available to everyone and anyone, and the use of the CAD/CAM technology should be able to take us there.
Then, when I was three years old, I had surgery to get a cochlear implant at the University of Minnesota. A cochlear implant is a small device which bypasses the damaged parts of the ear and directly stimulates the auditory nerve. Signals generated by the implant are sent by the auditory nerve to the brain, which recognizes t...
