Document Summary

Lecture 13: audition; perceiving the world around us. Example: on a guitar pull on chords and the sound comes from the air vibration around the chord. Vibrations create changes in pressure in the medium. The receiving of the mechanical energy that is pressure of air molecules against our apparatus. You have dense and less dense of air molecules to bump up against the ear. Different perceptions in these sounds: amplitude: difference between minimum and maximum pressure. Loudness (perception of intensity: frequency: number of peaks in one second measured in hertz (hz) Ear: properly shaped to capture sound waves. Eardrum: thin membrane (trampoline like) and moldecules push and indent the memebrane. The more sense the air molecules of sound the more it pushes. As sound continues the eardrum pushes in and out. Malleus&incus&stapes: attached to back of ear drum so they move back and fourth too. The stapes is connected to cochlea (hard structure)
