PSYC 2000 Lecture Notes - Lecture 5: Cochlea, Umami, Parietal Lobe
Document Summary
As we get older the ability to pick up high frequency noises diminishes. Sound waves are vibrations of the molecules of the air that surround us: acoustical transduction- conversion of sound waves into neural impulses in the hair cells of the inner ear. Pitch determined by the wavelength( peak of one wave to the peak of another) or frequency (low ,medium, or high) The pitch of a sound is based on what property of the sound wave. Determined by the amplitude or the complexity (richness) of the tone of the sound. The lower the amplitude the softer the sound. Around 85 db is where it becomes dangerous for hearing. The volume of a sound is based on what property of blah blah o. The quality of the tone distinctive of a particular singing voice or musical instrument. Outer ear: consists of pinna that collects & tunnels sounds o. Middle ear : chamber between eardrum and cochlea.
