Your bringing + i For us to hear sound we need two things (for audition to occur): together ting Meet Jin Pres 1. pressurized sound wave (a stimuli) together 2. hair cell (a receptor, located in the cochlea) sensitive to stimulus m What is a pressurized sound wave? Ex. In between your hands are a bunch of air breakdown molecules, and when hands move towards each other, there is less space so the sondwaves molecules compress and there is a higher pressure. The air molecules are becoming pressurized. . Air molecules are pressurized and try to escape, creating areas of high and low pressure – known as sound waves o Sound waves can be far apart or close together o Wavelength: how close peaks are. § Smaller wavelength = greater frequency. § Higher wavelength (smaller frequency) = travel farther = penetrate deeper into the cochlea. o Different noises have different sounds o You can listen to different frequencies at same time – if you add diff frequency waves together, get weird frequency. Ear has to break this up. Able to do that because sound waves travel different lengths along cochlea.
