A Cochlear Implant is a small, complex electronic device that helps individuals develop a sense of sound. This device provides direct electrical stimulation to the hearing nerve of the individual’s inner ear. Generally, people who are deaf or are hard-of-hearing use this this device. This device consists of external and internal portions that sit behind the ear of an individual and a second portion that is surgically placed under the skin. Cochlear implants give individuals the ability to make out sounds that those who can hear perfectly may take advantage of.
Interest in electrical methods that stimulate hearing came about in the late eighteenth century. Alessandro Volta discovered the electrolytic cell. An electrolytic cell is a cell that does work on a chemical system by driving an electrical current through the system. Volta was the first to stimulate the auditory system by connecting a batter of thirty or forty couples to two metal rods that were inserted into his ears. After the circuits were completed, Volta received a sensation of, “une recousse dans la tate.” The translation of that phrase means, “a boom within the head.” Several other scientists began to experiment with creations of their own auditory systems. In 1971, William House and Jack Urban worked together to refine cochlear implants that we know of today. These two researchers developed new devices that would be implanted behind one’s ear to give them the ability to make out sounds. In 1972, a speech processor was developed to work with the House 3M, a single electrode implant, which was first to be marketed commercially. Throughout the 1990’s, many science studies have resulted in the success of implant technology dealing with cochlear implants. Electrode and ...

...ithin the very world they are living in. Although these devices may be costly and include intense training, the outcome is great for those who use them. Individuals who use these cochlear implants are able to perform just as well as those who don’t have them. Several patients and families have shared their stories about how these implants have positively affected their lives. With these implants the overall well-being and quality of life for the individuals and whoever they interact with are made better. The invention of the cochlear implants was brilliant and life changing! It is truly amazing what this device gives individuals the opportunity to do. With more changes being made daily to ensure that these devices work efficiently and bring happiness to all users and those who encounter them, there is no telling when the greatness of cochlear implants will stop!
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.

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.
Metal alloys and precious metals are also used to make certain aspects of a cochlear implant. The electrode arrays that provide electrical stimulation in order to excite neurons are made out of platinum because they have very high corrosion resistance, good biocompatibility, easier to work with than iridium and have low chemical reactivity. On the other hand, metallic alloys like titanium are used to make the casing for the receiver/stimulator. Titanium is suitable for such an application because it is a light material with high corrosion resistance and rigidity and these properties are essential for the material that is going to be used to make the casing (Stöverl and Lenarz, 2009).
Specific Purpose: To help people to understand what Audism is and that the lack of an ability to hear does not mean they are incapable of performing tasks.

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.
Vestibular System Athletes must accomplish amazing feats of balance and coordination of the body. As scientist, Mikhail Tsaytin discovered in the 1970s, acrobats can successfully make a two person human tower in the dark, but after adding a third acrobat, not even the most talented can maintain the balance required to keep the tower intact while in the dark (1). What does darkness have to do with it? The point is that balance relies on at least three signals coming from the body, and one of those is sight. Once you eliminate one of these signals, the body cannot accomplish the required task.
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.
Several assistive listening devices can improve the communication ability of deaf children. According to IDEA, every child with a disability is entitled to have access to assistive technology (California Department of Education, 2004). The California Department of Education (2004) outlines IDEA’s definition of an assistive technology device. It explains that this device consists of “any item, piece of equipment or product system…that is used to increase, maintain, or improve functional capabilities of a child with a disability” (California Department of Education, 2004, p. 1).
While the idea of human tracking has its share of benefits, there certainly are numerous pitfalls that also exist. While the ability to identify someone with an ID tag may have practical uses, the security and privacy issues could seem potentially alarming to some. Not only that, a closer look may show that the technology doesn’t necessarily offer very many advantages when considering the costs of nation-wide adoption of the technology. This paper will try to investigate into these issues, whilst attempt to come up with some solutions.
.... There are devices for the television and the telephone and one-on-one communication. There are remote microphones that can help improve speech understanding in noise, a major obstacle for older individuals. Remote microphones can facilitate tuning in to the conversation for the individual with cognitive issues. For some hearing-impaired individuals implantable hearing aids have become an option. They do not require batteries and they do not have to be removed when sleeping or bathing. There are also rechargeable hearing aids, which removes the necessity for changing batteries, especially for those with memory issues.
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...
As the complexity and convenience of technology increases, some of the new advancements such as microchip implant for humans and animals can be very controversial. At first, the implants may seem to have benefits, but in the long run they will actually cause more trouble than they are worth. These potential "troublemakers" are about the size of an elongated grain of rice and are injected into the skin under the arm or hand (Feder, Zeller 15). The chip is not powered by a battery and there is nothing that can possibly leak out into the body (Posada-Swafford 8). An early form of this technology was used to monitor salmon and has been used for other wildlife research (Verhovek 5).
