Document Summary

The frequency of the wave is perceived as pitch and the amplitude is perceived as loudness. Vibrating objects produce a fundamental frequency as well as multiple overtones. The particular combination of the fundamental frequency and the overtones is perceived as timbre. Vibration event produce periodic sounds which are composed of regularly recurring pattersn. Friction and collision events produce aperiodic sounds that have no repeating pattersn and are perceived as noise. The organ of audio sensation is the cochlea. The cochlea is also called the inner ear. High frequency at far end and low frequency at near ear. Primary audio cortex is the in superior temportal lobe. Has the same tonotpic arrangement as te basilar membrane. Frequency is the number of wavelengths that pass by a given point in a certain amount of time. Sine waves are rare in natural world because. Frequencies that are higher than the fundamental that are also produced by the object.
