Document Summary

Compressed air represents peak of curve, less compressed air represents the valley (of graph) Volume: wave amplitude: higher volume, greater stimulus, greater amplitude; low volume = less amplitude. Pitch: wave frequency: low pitch = deep sound, what changes is frequency of sound wave how often you"re getting those bands within a period of time, higher pitch = higher frequency, pitch is detected in cochlea. Outer part of ear that you see: auricle / pinna(e) funnel sound waves from environment into external auditory canal. Tempanic membrane / eardrum: border between middle and inner ear, delicate thin membrane that vibrates when sound waves hit it. External and middle ear involved in sound, inner ear is involved in balance and sound. Rest of the structures past the external ear are embedded in bone, chambers and canals in the bone that create a space where these structures are located.
