    a type of deafness which is often caused by the damage on hair cells of cochlea in inner ears. Hair cells convert acoustic sounds to electrical signals and stimulate auditory nerves.

    membrane). Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate, and the vibrations are conducted to the nearby cochlea. The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals (labyrinth) attach to the cochlea nerves in the inner ear. They send information on balance and head position to the brain. The eustachian (auditory) tube drains fluid from the middle ear

    The public perception of the concept of deafness is often misunderstood, many deem it to be insignificant mainly because the struggle that these deaf people go through on a day to day basis seems invisible to the public eye. Hence, people might not be able to show as much empathy as they would to a person with say, an amputated leg. A common misconception would be how most people assume that when a person is deaf, they live in a world of silence. This is not always the case. On the contrary, there

The middle ear has two major functions, it not only protects the Inner Ear but also transforms the quivering of the air coming from the outer ear into vibrations that the inner ear can analyze.

    Helen Keller once said, “Blindness cut us off from things, but deafness cuts us off from people.” Throughout her life Helen Keller understood how important and enlightening being able to communicate with others is. Helen Keller had many challenges and misconceptions that she had to overcome, as do all deaf people, because even though deaf people can learn to communicate, there are numerous barriers in our predominantly vocalized world.

    In Audism Unveiled, the producers included subtitles for the signing-impaired, and I thought this very important dialect because normally movies include subtitles for the deaf or hard-of-hearing viewers. However, it is very significant to emphasize that it is not the deaf community that needs auditory assistance but rather the hearing community needs assistance to fully understand the meaning of sign language. Audism was coined in 1975 as a term to place advantage upon hearing people and should

    Deaf in the Military “Sorry, no. You’re deaf.” That is what Keith Nolan was told too many times to count. Because of ideologies, the general public considers deaf individuals to be handicapped or disabled. However, this is not the case. Those who are deaf or hard-of-hearing are more than capable of doing most of the things hearing people can do. In this paper, I relate the Ted Talk, “Deaf in the Military,” to communities of practice. After investigating and writing the research paper, “Deaf in the

    I watched Sound and Fury, a documentary that came out in 2000, centered on the complications of getting the Cochlear Implant, and how Deaf and hearing communities can differ upon the topic. Particularly within one family, brothers along with their wives and parents have a tough time deciding if their Deaf children should undergo such a procedure. They all travel to visit families that are hearing with children who aren’t learning ASL because they have the implant. They visit a Deaf family whose 10-year

He started off with a computer in his head that enabled him to hear, it was also called the cochlear implant. Drawing on that experience, he then proposes that our Paleolithic bodies and our Pentium chips could be physically merged. After Chorosts’ failure on

    Imagine a world were you could not hear. The world would be mostly silent and you would have to rely completely on your other senses. This is what a deaf child encounters every day. When the word deaf is used it is referring to all levels of hearing loss. This includes partial loss, total loss, and everything in between. Deafness occurs when any part of the ear is not working correctly which inhibits the child from hearing correctly. This could be caused by genetic factors, prematurity, maternal

    Over the years the deaf community has been called “deaf and dumb” or “deaf-mute”. Little do people know that they that in reality they are very intelligent people. Not only are they intelligent but they are not mute. It is impossible to speak if you cannot hear those two go hand in hand. Just because they cannot hear does not mean that they should be called such a thing. Hearing does not necessarily mean that you are smart nor does not hearing mean you are dumb. Over the years these terms became

    Before I saw the movie I thought it was just going to be another regular documentary. While we were watching the movie I realized it wasn 't at all what I had expected. It changed my perspective on the deaf community. The film allowed us to see into their world and let us know they are no different than hearing, if anything it seemed to me like they have more fun. There were so many different people that spoke throughout the movie, and every single one of them seemed so happy. Throughout the movie

    Is it morally permissible for a deaf couple to select for a deaf child? Would it be acceptable if the preimplantation genetic diagnosis provides the opportunity and hearing impaired parents choose to have a child with hearing disability? Some people draw parallels with intentionally harming a baby, e.g. depriving the child of his/her hearing sense . Thus, they say, it is unethical. Some people argue that by choosing the child with disability it harms the society . However, ethical considerations

    During my time at Highline I became involved with the Deaf community which I previously had no idea existed. My original interest in learning ASL was sparked by my nephew who relied on the language as his main method of communication due to a processing issue in the Wernicke 's area of his brain. He was completely capable of understanding speech, but signing was easier for him to use for self expression, yet his family simply refused to learn the language. I thought this was nonsense and decided
