Document Summary

Sound waves are periodic compressions of air, water, or other media. The amplitude of a sound wave is its intensity (bolt of lighting produces sound waves of great amplitude. Loudness sensation related to amplitude but not identical i. e. a rapidly talking person sounds luder than a slow music of the same physical amplitude. The frequency of a sound is the number of compressions per second, measured in hz. Pitch is the related aspect pf perception: higher frequencie sounds are at a higher pitch, most adult humans hear sounds ranging from about 15 hz to somewhat less than. *height of each wave corresponds to amplitude, and the number of waves per second corresponds to frequency. Complex like rube goldbergs device (w/ cat) but works. Pinna fleesh and cartaliage attached to head by altering reflections of sound waves it helps us locate the source of a sound outer ear.
