Cochlea

. The ear is made up of three parts: the outer, middle, and inner ear.The outer part of the ear collects sound. Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum. Sound entering the outer ear travels through the middle ear and causes the eardrum and ossicle in the middle ear to vibrate. As it travels, it amplifies and changes from air to liquid. When the stapes moves, it pushes the oval window, which then moves the cochlea. The cochlea takes the fluid vibration of sounds from the surrounding semi-circular ducts and translates them into signals that are sent to the brain by nerves like the vestibular nerve and cochlear nerve. In order to hear something which is very loud or any whispering, sound…

bone oscillator vibrates the mastoid bone and thus the skull. The skull creates vibrations in the cochlea, displacing the endolymph and creating sound waves back through the inner ear to the middle ear and then to the outer ear canal. In an unoccluded ear, these vibrations would escape out the exterior auditory canal. However, when the ear canal is occluded, the sound waves have no where to go and therefore circulate in the ear canal layering on top of one another causing an increase in their…

she had to make the riskiest decision of her life, which is getting a cochlear implant on her right ear. The main reason why it was chancy because under eighteen years old, she could get the surgery for free from insurance, so she wanted to take advantage of that. Back on topic, quoted from Google, “A Cochlear Implant is a device that can be surgically implanted into a person 's cochlea to stimulate it to cause hearing. It consists of a tiny receiver which is placed under the skin in the bony…

problem with their ears, and the one major dis-advantage that led people using hearing aids is deafness, now people may ask what deafness is. Well it is a disease that might hit you when new babies are born, or sometimes when you here a loud sound like an explosion that’s in front of you, furthermore, if deafness hits you it might be either mild, moderate or sometimes profound; it can effect either one ear or two ears, and if people lose their hearing ability they would have a really tough time…

born without ears. Because few cases of deafness are the same, many decide to use cochlear implants. Cochlear implants completely bypass the ears and send information directly to the brain. They consist of two main components: internal and external. The external component worn behind the ear contains a microphone, a speech processor, and a battery compartment. The internal component consists of tiny electrodes inserted into the cochlea and an electric device that is implanted behind the ear…

in the United States. “In the United States, approximately 1,000,000 people (0.38% of the population, or 3.8 per 1,000) over 5 years of age are "functionally deaf" (Mitchell). Fortunately, for some, there is help. A cochlear implant is an electronic medical device that does the work of damaged parts of the inner ear (cochlea) to…

Rene Gifford continues to seek ways to improve them and in turn increase the hearing of their patients. This wasn’t a controversy in the sense that there were arguments or debates in the scientific community, but after all the research conducted with these implants; there were debates on how to improve them and the methods that would bring about the most significant enhancements. So What? Rene Gifford and her team had a theory on how to develop methods to improve these implants for their…

premature ear structures (Schwartz, 1996). Maybe a sign of undiscovered hearing loss is a person’s slurred and improper speech (Schwartz, 1996). When someone has mixed hearing loss, he or she has sensorineural hearing loss and conductive hearing loss (Schwartz, 1996). When spiral ganglion neurons stop sending nerve impulses from the cochlea to the brain, and there is a loss of sensory hair cells in the ear, deafness occurs (Chen & et al., 2012). About four-thousand newly born babies in the…

In recent years, numerous technological advances have come forth in an attempt to resolve or dampen the effects of different sensory impairments. Since around the intermediate years of the 1900s, one invention in particular has been designed, revised, and debated over with the purpose of aiding individuals who suffer complete and various partial forms of hearing loss. Hearing loss involves cochlear malfunction, and the cochlea is the primary hearing organ in the inner ear. Over the past few…

I haven’t realized that the mechanism for us to hear the music is quite different from the languages before. This video reminds me of one of my classmate in middle school, who is born deaf and had the cochlear implant. He could communicate with us but his pronunciation is slightly different from us. It happened almost ten years ago and I am not sure whether the cochlear implant devices have been greatly improved nowadays. According to the video, the modern multi-channel cochlear implant device…
