Sound Waves Affecting The Brain's Perception Of Sound

Decent Essays

The normal range that humans are able to hear from is 20 hz to 20kHz. The average human can hear up to 20 hertz, After using the resources provided in Physics class I discovered I can hear between 19hz and 20hz. I could sometimes hear the 20hz but sometimes I could not. I am about average for the highest frequency I could hear. Sound is made of pressure waves which when they travel oscillate or vibrate. Each wave travels at a certain frequency based on how much the sound moves. Sound is created when air molecules are pushed in a certain direction causing them to vibrate. This creates sound waves. Sound moves by vibrations and are caused by compression or some form of pressure. The higher frequency at which the wave oscillates the higher the …show more content…

Based on the second resource in Physics, I could not district between frequencies as well as I should. My issue was could tell there was a difference in pitch I just could not tell if it was higher or lower once they got super similar to one another. The biology behind it is that once a pitch has traveled through the ear and the cochlea has transferred it to the brain, the arcuate fasciculus produces the process of distinguishing which pitch is higher or lower than another. Some people can do this better than others based on the way their brain works. But it is all pitch recognition in your brain. Tiny sound waves inside your ear help you tune the pitch and pick up sound waves. They take the sound waves and turn them into nerve signals causing the brain to interpret sound. The enter form the outer ear and travel through the passage of the ear canal. It then reaches the eardrum where the vibrations translate into the sound we hear. It then goes to the cochlea, a snail-shaped structure that contains fluid in the ear. The sound causes the liquid inside to ripple. The wave goes across to the basilar
