The Auditory Pathway Analysis

When a person with normal hearing hears the sound travels along the ear then bounces against the ear drum. The eardrum, the bones inside, and the cochlea vibrate and move thousands of tiny hairs inside the ear. When these hairs move an electrical response occurs. This electrical response goes to the hearing nerve and then it is send to the brain.

Basically how sound travels through the ear is a process of many steps. The sound waves are gathered by the pinna and then funneled into the meatus. Those waves then begin to vibrate the tympanic membrane which in turn hits against the malleus. The ossicle bones then vibrate like a chain reaction. The footplate will hit the oval window which triggers the fluid in the cochlea to move. The movement sways across the different hair cells creating impulses that are sent to the brain through the eighth cranial nerve.

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

interpreted by sound receptors on the skin. This is transmitted to the brain for integration before

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

Since the age of 2, Brandon Edquist has been deaf since he was two and when he turned three, he got a cochlear implant as said in his interview with INSIDER. Edquist describes his experience living with his implant being unbearable. His cochlear implant created artificial ringing noises that distracted him from being able to focus on other sounds. Once Edquist began to learn how to associate sounds with specific words with the help of physical therapists, he felt frustrated most if time by the difficulty it was for him to learn, plus, he recalled, how it was difficult to differentiate sounds because to him they seemed the same. According to the National Institute on Deafness and Other Communication Disorders, “About 2 to 3 out of every

Explain that wearing the aids as often and as consistently as possible is essential to speech and language development for the child. The hearing aids provide access to sounds for the child and without this stimulation speech and language development will be negatively impacted. Auditory input is needed to help the child to learn to listen, if the aids are not being used and the auditory pathways of the brain are not being stimulated then the child will eventually lose that ability. The quality of the signal in the hearing aids is directly related to the child’s speech intelligibility. A high quality auditory input provides a better opportunity for learning and better speech intelligibility. Full access is important for children who are learning

Medical professionals all over the world have paved the road for further research and technological advances in the hearing impaired spectrum. Implantations, such as the cochlear implant (CI), have given patients with profound sensorineural hearing loss newfound hope for habilitation and rehabilitation services. However, “there exists a small subset of deaf individuals who will not benefit from the CI due to (1) a small or absent cochlea, (2) a small or absent auditory nerve, or (3) injury or scarring of the inner ear or auditory nerve secondary to meningitis, trauma, or tumor” as stated by Kaplan et al. (2015). A treatment option for those who did not meet the candidacy qualifications for a cochlear implant needed to be implemented.

Hearing serves a crucial benefit for understanding the world around us. During the 1940’s, Dr. Ramsdell realized that hearing serves four crucial function; symbolically we are informed or entertained, aesthetically hearing is naturally pleasing, warningly we are alerted or prepared, primitively we are aware of our surroundings [1]. The ear is typically divided into three sections, used to simplify the hearing process. The first section, or the outer ear, is composed of the auricle (skin covered cartilage), the auditory canal, and the tympanic membrane (the outer layer of the eardrum). The middle ear section contains the eardrum, tympanic cavity, and the ossicles. These ossicles are three small bones often referred to as malleus (hammer),

The main device that humans have that receive sound waves is the ear. The ear is shaped similar to a funnel and that allows it to collect the different sound waves that can reach it but , the brain is responsible

The ear is made up of three parts: the outer ear, the middle ear and the inner ear. The outer ear is responsible for collecting the sound wave, the middle ear increases the sound energy and transmits the sound to the inner ear and finally the inner ear transforms the sound waves into nerve impulses and sends them to the brain. When the sound wave passes the ear canal there is a vibration in the eardrum which affects 3

This article seeks to identify whether or not children who have received a cochlear implant before the age of 3 reach expected language abilities for their age group by mid-elementary school. According to the article, many children with cochlear implants have normal language development while some have a slight language delay but are able to reach age appropriate language ability by mid-elementary school. However, there are a significant number of children with cochlear implants who continue to have language delay throughout elementary school.

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

Sounds and speech are captured by a microphone and sent to the external speech processor. The processor then translates the sounds into electrical signals, which are then sent to the transmitting coil. These codes travel up a cable to the headpiece and are transmitted across the skin through radio waves to the implanted cochlea electrodes. The electrodes’ signals then stimulate the auditory nerve fibres to send information to the brain where it is interpreted as meaningful sound.
