Document Summary
Timbre vibration of acoustic instrument that are set up by pitch: makes same pitch & volume on different instruments sound different sound wave, resonance vibration set up in object when presented w, occurs in acoustic instruments (piano, violin, timbre made of combination of resonances carried on pitch, structures of ear. Outer ear collect and bring sound wave to middle ear: pinna, auricle, lrg extension on out ear, used to capture waves, opening that exists in out ear, funnels sound down external ear canal to tympanic membrane, ear canal, tympanic membrane. Transmitting energy through increasingly smaller surface area to the stapes (stirrup; part of inner ear: stapes: stirrup ; part of inner ear that receives energy, 100 fold amplification of force from ossicles, oval window, round window, inner movement of stapes corresponds w/ outer movement of round window, relieves atmospheric pressure, system can amplify sound has dampening system, attenuation reflex, tensor tympani malleus; stapedius stapes.
