Hearing loss can happen to anyone and it occurs as a 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 …show more content…
They are a highly efficient and worthwhile treatment of severe to profound sensorineural hearing loss in children and adults. They have made it so that prelingually deafened children can develop near to normal levels of speech and language. Furthermore, postlingually deaf adults and octogenarians- people from 80-89 years old- can usually speak on the telephone and achieve normal levels of speech understanding in quiet environments within a year of the implantation.
One type of cochlear implant is being developed by the National Physical Laboratory (NPL) that will allow deaf people to hear sounds over a wide range of frequencies, including music. Most cochlear implants focus on the frequencies most prominent in the human voice, which isn’t good if one wishes to listen to

Cochlear Implants

...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.

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.

Deaf people have tended toform deaf communities because of deaf pride, and a belief that they do not have adisability. However, this has led to a barrier between deaf and hearing people, and thesebarriers can lead to consequences because many hearing people do not know how tointeract with deaf people. Even people who are deaf or hard of hearing and that are notpart of a deaf community (such as if they chose to attend public school rather than aschool for the deaf) can have much difficulty when communicating with hearing people.Problems with communication occur all over the place for deaf people such as within afamily, in school, in the workforce.When a child is deaf, but his or her parents are hearing, it can create manyproblems with communication. If the parents have little or no experience with deafpeople, they will face challenges at first before they learn sign language and learn how toaccommodate their child. If parents don’t know how to properly communicate with theirchild, they will have problems raising them. With communication problems will cometrouble because they wont know how to scold their child or tell them when they are doingwrong, make their child feel included and a part of the family, and be a normal lovingparent.

..."MY TEACHER, MY HERO" In life, people may come and go, some will be remembered and some are forgotten. But one thing is for sure, I'll never forget the person who is known as my second parent. Who did efforts for me to gain knowledge, the one who has been my guide for so many years, the one who scolds and corrects me when I am doing wrong, the one who has been there as I face to reach the stepping stones in my life. The one who appreciates my efforts, the one who is always there to feed me a bit-full of information that I might use someday, the one who saves me from this unfair life where everyone should be feed with the same level of knowledge. The person who sacrifices for our own good, and yet, the laziness that I've shown them, the tiredness that they have seen from me. After all, they never give up and they never stop to fill us with knowledge and when we are going to fall, they are always there to reach our hand and pull us back and so, the years might have been overthrown, and everything will fade, but they always be my hero for life and for all that efforts and sacrifices that they've done for us. How would life be without our teacher? In life, people may come and go, some will be remembered and some will be forgotten. But one thing I am sure of, you can never forget the persons who you can also call as your second parents. Your teachers. When we’re talking about our teachers, all of us are glad to thank them especially when you’ve learned a lot of great lessons...

Special Education

...Chapter 1: Student Characteristics Understand Characteristics of Students with Disabilities Some students with disabilities pass through typical developmental milestones and express skills within an average range for their age group. Others show delayed growth at certain developmental milestones, and many students with disabilities experience challenges as they navigate through the school curriculum. It is critical that special education teachers know how to differentiate between typical individual differences among children without disabilities and differences that may indicate a disability that requires interventions and/or specialized designed instruction. In addition, special education teachers need to know the most common types of disabilities that students may experience and how those disabilities affect their ability to learn and their behavior in the classroom. Competency 1 thus focuses on the characteristics of typical and atypical human growth and development and the characteristics of students with various disabilities that special education teachers are likely to encounter. The test includes a wide range of multiple-choice questions that address Competency 1. * Questions on typical and atypical behaviors and abilities for children and adolescents at particular ages. * Questions on the types and characteristics of various disabilities. * Questions on the similarities and differences among students with and without disabilities.
