...consequence of cochlear hair cell loss. The tip of the nerve fiber tuning curves expand through the loss of compression at the characteristic frequency and through the loss of hair cell controlled by elimination at neighboring locations. Sadly, hearing aids, no matter how advanced, cannot replace the nonlinear system of a healthy cochlea as they only amplify sound, they don’t make it clearer. Luckily, there are such things as cochlear implants, which offer a greater chance of success at restoring clarity and meaning of sound eroded by hearing loss than hearing aids do. A cochlear implant is a small electronic device used to treat severe to profound hearing loss. It’s implanted beneath the skin, behind the ear, and it provides direct stimulation to the auditory nerve in the inner ear. The implant does not restore normal hearing, but it does improve sound detection and speech understanding, and it increases the amount of nervous response to sound. Adults who have recently...

...Cochlear implants are one of the many topics included in the vast collection of things arguable in today's media and social setting. There are endless accounts of opinions and views that go on inevitably, unfortunately. And the bickering throughout the hearing community, as well as the deaf community, continues. Some people think cochlear implants are substantially terrific and that the heavens must have graciously blessed them so that their particular child could "be normal". But others refuse the whole idea of cochlear implants being an acceptable notion. But, I propose a question: since when is it a bad thing to be deaf? The deaf people I have encountered are glorified and everybody wants to know them and learn sign language just to interact...

...Cochlear Implant Essay Jeanie Partlow HCA/COMM 270A The Context and Language of Health Care Randi White Warner Pacific College April 30, 2012 Cochlear Implant Essay A cochlear implant is a surgically implanted device that provides electrical stimulation to the auditory nerve in the inner ear. The device has internal and external components. The external parts consist of a microphone, a speech processor, and a transmitter. The internal parts include a receiver and electrodes. The external speech processor captures sound, converts it to digital code that is transmitted to the internal electrodes, and finally, communicated to the brain for interpretation as sound. Good candidates for the cochlear implant have profound bilateral sensorineural hearing impairment and functional auditory nerves. Three groups of patients that have the greatest potential success include post-lingually deaf adults, pre-lingually deaf children, and post-lingually impaired people (usually children) who have lost hearing due to diseases such as meningitis. Tyler, Fryauf-Bertschy, Kelsay, Gantz, Woodworth, Parkinson (1997) confirm pre-lingually deaf children are excellent candidates as they obtain the implant during the time that the brain is developing and highly functional in adapting to sensory input. The cochlear device is implanted behind the ear where the surgeon will create a pocket in the mastoid bone for the receiver. The electrode array is then placed through the inner ear into the cochlea...

...Characteristics of Expository Essays What Characteristics make these essays expository? The two essays I chose to read were “Cochlear Implants” and “How to Clean a Fish.” When reading “How to Clean a Fish” the characteristics that make this an expository essay is that the author used facts to back up his or her opinion. The essay was very informational and used a great deal of detail on “How to Clean a Fish”; also the essay broke it down for you with diagrams and details. The essay was also presented in a non-bias manner. When reading “Cochlear Implant” the characteristic that make this an expository essay is that the author uses the facts to back up his or her opinion, the essay is very informational and gives examples of why the implants will work for someone that was deaf. This essay also was presented in a non-bias manner as well. Indentify the type of organizations each author used to develop the essay: topic, time order, space order, or informative process? Why do you think each author chose that type of organization for his or her essay? In what ways does this organizations choice make the essay effective? What effect might the author have achieved with another type of organization or another type of expository essay? I believe the author in “How to Clean a Fish” uses the informative process to arrange his or her essay.

...Communication 389 CSULA Summer 2014 ICC Artifact Two 7/27/14 ICC Artifact assignment: The Cochlear Implant Controversy According to our text in Chapter 7 Nonverbal code and cultural space there are certain aspects of the culture and its relationship to nonverbal activity. Personal–contextual and the static–dynamic dia- lectics. Although nonverbal communication can be highly dynamic, personal space, gestures, and facial expressions are fairly static patterns of specific non- verbal communication codes. Their interpretation will vary depending upon its context and culture that it is being communicated to. The chapter talks about how different the dynamics of intercultural nonverbal communication are across different cultural groups. In this ICC artifact assignment we will examine and look at the topic of The Cochlear implant controversy. The controversy involves the scientific hearing assistance breakthrough device for the deaf community, and whether or not its use and development will be the ultimate removal of and extinction of the deaf community as a culture. The following essay will examine the relevance and truth to this argument and examine the negative and positive manifestations to the Deaf culture from the development and use of the Cochlear Implant itself. The Chapter talks about several research findings about nonverbal communication. Research investigating the universality of nonverbal communication has focused on four areas: (1) the relationship...

...Running head: Career Research Essay: Career Development Career Research Essay: Career Development Career Research Essay: Career Development Abstract Audiology was born out of the armed forces rehabilitation programs during and following WWII. The practice has expanded to include both diagnosis and treatment. Audiologists specialize in hearing and balance disorders. To become an audiologist, a doctoral degree is needed. It is an Au.D. earned from a program accredited by the CAA. These programs last at least 4 years. Audiologists held about 12,800 jobs in 2008, and about 13,000 jobs in 2012. Audiologists work with patients of all ages, from newborns to elderly. Keywords: Audiology CAREER RESEARCH ESSAY: CAREER DEVELOPMENT Audiology was born out of armed forces rehab programs during and following WWII, as many soldiers sustained injuries to their inner ears from loud noises. The practice was largely influenced by the invention of hearing aids-originally, audiologists could recommend amplification, but could not provide it. The Academy of Doctors of Audiology was formed in 1976, and audiologists moved beyond technician status. The practice then expanded to include both diagnosis and treatment. “Audiologists specialize in balance and hearing disorders. They diagnose hearing, neural, and balance disorders in patients from all age groups and recommend solutions to correct or cope with problems. To diagnose and correct balance and other hearing related problems...

...One study compared fixed and Dynamic FM performance for hearing aid users, while the other made the same comparison with cochlear implant recipients. In the hearing aid study, conducted by Dr. Linda Thibodeau, both adults and children (ages 11 tol5) were used as subjects, and both objective and subjective measures were taken. The objective comparisons were conducted in a large classroom, with the interfering noises - ranging from 54 dB to 80 dB - emanating from four speakers located in the corners of the room. The FM microphone was placed six inches from another loudspeaker located in the center of the room. The goal was to create a situation where someone would talk into an FM microphone while the listener was surrounded by changing levels of ambient noises. For the subjective comparisons, the subjects tried both the fixed and the adaptive systems at home and during activities in a public aquarium. As expected, the objective results show no difference between the two systems at low noise levels. This is because the adaptive feature is not triggered until the background noise level exceeds 57 dB. But as the noise level increased, the speech perception scores increased with the adaptive system only, reaching a maximum difference of about 50 percent at the higher noise levels. Across all noise levels, the average difference between the fixed and the adaptive systems was about 25 percent. Subjectively, too, most or all (depending upon the activity) of the subjects preferred the...

...Observation Tuesday, June 16, 2015 Tricia’s Sunflowers, Perry, UT (In-Home Daycare) 9:30 – 11am In this observation, I will refer to the child with a hearing impairment as B. When I first stepped into the room where the child with the hearing impairment was, I immediately noticed a few things around the room that were put there specifically for her. There were flashing lights right next to a clock and there were pictures of ASL signs next to written signs in the room. Right away, I could tell the teacher in this room really took the time to see what she could do to assist in communication. This room has six children, all between the ages of 3-5, and B is the only child who has a hearing deficiency. B wears a hearing device, a cochlear implant, to help her hear better and understand the other children. Although she is encouraged to keep the device on at all times during school, aside from nap time, B will take off her device if she is upset, needs quiet time, or is not feeling well. I arrived just as the children are beginning their morning group session. The teacher in this classroom, Ms. Tricia, knows ASL because she taught her children ASL when they were babies and toddlers to assist in communication. During morning group, as the teacher is talking, she is also signing to B who is sitting in the front and center of the group. It is interesting and heartwarming to see the other five children attempt to sign along with B and the teacher as they sing their morning songs...

...24th October 2013 Reflective Practise Piece Description The patient was attending, on her own, a 60 minute consultation with the resident Hearing Aid Audiologist. The lady came to us having been recommended by word of mouth by family and friends. She had been tested 6 months ago by another Specsavers Hearing practice, so access to a previous audiogram revealed a mild to moderate sensorineural hearing loss. No other case notes were available at the time of the consultation. Key Issues The key issues I found particularly interesting were: 1 Communication between the patient and the audiologist 2 Impact of case history forms 3 Hearing loss stigma Reflection and Influencing Factors According to Maltby (2009) client –centred problems solving is the most widely used approach to adult aural rehabilitation. I was keen to observe the rehabilitative process and reflect on its benefits. The audiologist was informed of the arrival of the patient and called the patient through to the consultation room. Formal introductions were made. Although the patient had previously had a hearing test, she seemed uneasy and a little tense. The audiologist explained the consultation process so the patient would feel more relaxed about the test. The standard questions from the case history forms were asked and during the case history the patient started to relax and made much more eye contact with the audiologist. When asked if she felt she had a hearing problem she...

...view it as a distinct culture that is not in need of rehabilitation; however, cochlear implants allow a deaf child to grow up in a hearing world. Allowing a child the opportunity to hear will allow them to have several benefits compared to a life without having the opportunity to hear (McKee, Schlehofer, & Thew, 2013). Such benefits include having an increase in the child’s language development (Dettman, Pinder, Briggs, Dowell & Leigh, 2007), having an improvement in peer relationships (Martin, Bat-Chava, Lalwani, & Waltzman, 2011), and having an improvement in the child’s overall quality of life (Schorr, Roth, & Fox, 2009). The first benefit a child could experience with the use of cochlear...

...A cochlear implant is a medical device that is implanted into the head behind the ear of a deaf person. It is very different from a hearing aid. Hearing aids magnify sounds so damaged ears may identify them. Cochlear implants escape damaged areas of the ear and activate the auditory nerve directly. Signals made by the implant are sent from the auditory nerve to the brain, which recognizes the signals as sound. Hearing through a cochlear implant is not the same as normal hearing and takes time and practice to learn or relearn. On the other hand, it allows many people to identify warning signals, recognize other noises in the surroundings, and enjoy a talk in person or by phone.(National Institute on Deafness, 1) When the device was first developed...

...occurs when very loud sounds damage hair cells. One example of this is listening to loud music. These hair cells are very small, and also very fragile. Dead hair cells can never be replaced. Once they are gone, they can never be replaced. A study showed that was you are sixty-five years old, more than forty precent will be gone. Emily can not get a hearing aid because, hearing aids are no help in case of sensorineural hearing loss because auditory messages are blocked from reaching the brain, as of yet there is no cure for high frequency hearing loss. Emily can receive treatment, which focuses on improving hearing rather then restoring it. Many cases the auditory nerve is actually intact. Emily can act on her hearing loss by getting a Cochlear Implants. Its job is to bypass hair cells and stimulate the auditory nerves directly. I think that this will help Emily because if the auditory nerved is intact, it is possible for Emily to still hear and will not be forced into deep anxiety. But if in fact its not, then its nothing she can do to help herself. When Emily hears the strange noise, because of her hearing problem, it reminds her of her mother. Many people are driven into compulsive behavior because of events in their lives. Emily event in her live that causes compulsive behavior is when her mother was fighting cancer and makes a little groans noise. When she was little she heard this groan from her mother all the time, and that was something she...

...The Silent Society: Being Deaf Deafhood and Epistemology When considering the epistemology of deafness, one must consider the history of how deafness has evolved. The history of deafness comes from the ignorance of those who could not understand how people who had a disability were different from them. It was easier to place these types of “folks” in intuitions and not deal with their needs. Understanding the deaf community comes through understanding the culture and the history that allows the deaf to have a “voice” and provide them with the necessary services that make the deaf more human. Through mental health, hearing assessments, and trauma, there is an understanding that even though they may not live in the hearing world, there are still apart of society. How they function as a community is important, as they too have a voice. Deafhood is described as “static”, not a medical condition; however, it is a process-a struggle that is endured by every child, adult, and family to explain themselves, and each other their own existence within their world (Hauser, O’Hearn, Steider, &Thew, 2010). Epistemology can be defined as the philosophy that investigates the origin, nature, methods, and limits to human knowledge. When dealing with deaf epistemology, there are many facets to which it can be understood and misunderstood. The authors discuss the visual learning process that a Deaf child goes through by being raised by either a Deaf parent or a hearing parent....

...Mixed hearing loss is a combination of conductive and sensorineural. Central hearing loss is a problem in the central nervous system involving the inability to interpret sound. Functional hearing loss is caused by an emotional or psychological factor in which there is no physical finding of hearing loss (Lewis et al., 2011) Mosby and Elsevier (2009) (Crusse & Kent, 2013). To determine the type of hearing loss, type of hearing device needed and proper fit, there are different doctors with different levels of education a person can see. Choosing a correct hearing specialist is important. An Audiologist can identify and access hearing disorders. They can also select and correctly fit hearing aids. Audiologists can also program cochlear implants and provide counseling services, rehab and instruction on device usage. An Audiologist is required to have a doctorate or masters degree. A Hearing Aid Specialist can access, select, fit and dispense hearing aids. The can also instruct rehabilitation and counsel in use and care of hearing aids. A certification by the National Board of Certification in Hearing Aid Sciences is...
