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 ...

Users Of A Cochlear Implant Essay

- Users of a cochlear implant (CI) have significant problems understanding speech in a noisy environment, despite their good performance in quiet (Wilson and Dorman, 2008a,b). Speech intelligibility in noise can be improved by adding an (amplified) low frequency acoustic signal to the electric stimulation of the CI to the same or to the non-implanted ear (e.g., Cullington and Zeng, 2010; Dunn et al., 2010; Sheffield et al., 2015). The combination in the same ear is called electro-acoustic stimulation (EAS) and its use has proved beneficial even if only low frequencies are present via acoustic stimulation, e.g., frequencies with as upper limit the speaker 's fundamental frequency (F0) (Zhang et...   [tags: Sound, Acoustics, Frequency modulation]
