Ear Lab Report

send this information to the central nervous system. The motor neurons in turn carry processed

The receiver is located adjacently to the transmitter on the other side of the skull and attaches to the electrode array. These two components are internal devices, with the electrode array going through the ear canal and cochlear. The receiver induces the electric impulses along the electrode array to stimulate the hearing nerve fibres in the inner ear. Signals are then sent via the hearing nerve to the brain and recognised as sound.

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.

Hi Amy. I have just wanted to expand on your post. In the beginning of chapter 10, Sacks explores medical history. He argues that the course taken by sound vibrations, from their entry into the external ear canals, through the eardrums on either side to the small bones, the ossicles, of the center ear, to the snail-molded cochlea, was initially worked out in the seventeenth century. It was believed then that sounds were transmitted by the ear, becoming enhanced in the cochlea "as in a musical instrument." After a century, it was found that the tapered shape of the cochlear spiral was differentially tuned to the scope of discernable frequencies, responsive to low sounds at its wide base, high sounds at its narrow apex. At last, by 1700, it was

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)

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

Have you ever wondered why our ears are shaped the way they are? The curves and dips in or ears help us receive the longitudinal waves in the air. After we hear a noise, the temporal lobe in our brain allows us to comprehend that sound.

Bionic ears capture a sound or voice and make that sound into a digital code. The digital code runs into the eardrum and the malleus, which is a small bone in the ear that transmits vibrations. The wires run down the top of the outer ear and then run to the eardrum then to the cochlea. The bionic ear wire slides inside the cochlea and contacts where the hearing nerve was. The implant stimulates the nerve that sound travels through the cochlea. The implant acts as a simulated cochlear nerve that sends impulses to the brain as sound.

After watching Kelly and analyzing the actual surgery of the cochlea implant, the inner ear and how we receive signals makes more sense. To be honest I had to watch this video multiple times and look up ways they perform the surgery to get a better overall understanding. However thinking about how we pick up noise and hear sound differs between each individual, such as light. It all depends on our hair cells, which

The ear is made up of three parts, the outer ear, the middle ear and the inner ear. The outer ear consists of the pinnae. Its function is to focus sound on the tympanic membrane. The middle ear is where the three ossicles are containes, the Malleus, Incus,

Hearing allows her to communicate with others be involved about what’s happening around us. As we know the ear is connected to other parts such as the mouth the nose and the brain as well. The nerves of hearing are the pathway and connection to our brain. It allows the brain to process sound such as the pitch and volume. The ear has three parts.

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected, absorbed, and also filtered by our different body parts. It's then collected by our pinnae (the external part of or ears), whose dimensions further affect the sound on its way into ear. There, vibrations are translated into signals, which are interpreted by your brain. In the 1930s, two scientists at Bell Labs, Harvey Fletcher and Wilden A. Munson researched this process and what they discovered has changed and affected how we as humans understand the hearing process.

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 ear has several different mechanisms inside enabling the perception of sound from the environment. Bringing me to the next step of the perceptual process, neural processing. In this stage the receptors transmit signals via neurotransmitters through the auditory nerve and eventually into the brain. The cerebral cortex is responsible for turning the signals into my perception of the music.
