More Than Meets The Ear Analysis

In this essay I will be discussing my three ideas from chapters 4,5, & 6 that I found interesting and why I found them to be interesting to me. Chapter four was about Sensation and Perception, the section I found to be of most interest to me was about Audition: More Than Meets the Ear. The ear anatomy consists of the Outer Ear (pinna, ear canal, & ear drum) Middle Ear (ossicles-malleus, incus, & stapes) Inner Ear (cochlea, auditory nerve, & brain). With normal hearing the sound waves enter the ear canal which makes the ear drum vibrate. This action makes those tiny little bones in the middle ear move. Once the sound waves reach the last bone it then knocks on the cochlea. The fluid movement then triggers a response to the auditory nerve to the brain. Someone without normal hearing can have many reasons why. They could be from just an infection, …show more content…
I can relate to how the ear functions because I have a conductive hearing loss. My ossicles is damaged, the incus doesn’t move in my left ear. So therefore, sound waves enter the ear canal and make their way to the ear drum. But once the sound waves reach the ossicles the sound waves are then broken up and not all the sound waves make it to the cochlea. To fix that problem a hearing aid comes into play. With a hearing aid the sound waves go thru a microphone, which converts the sound waves to an electrical signal and sends them to the amplifier. The amplifier then increases the power of the signal in the auditory nerve to the brain. Chapter five is about Consciousness, the idea that most interested me in this chapter was Sleep Disorders. I learned more about them and what their outcomes could be if there not dealt with properly. Sleep disorders are the changes in sleep patterns or habits that can negatively affect your health. There are several sleep disorders, the most common are:
Insomnia- difficulty going to sleep or staying
