    . 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…

    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…

    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…

    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…
