Document Summary
Localizing objects is the domain of vision, but the auditory system is also efficient @ indicating object position in addition to object presence. The properties of sound: understanding how the brain creates the experience of sound. Frequency refers to the rate of vibration or the number of waves cycles completed per unit of time indicated in hertz (hz), which is measured in cycles per second. Humans are most sensitive to sounds btwn 1000-4000 h (roughly the frequencies of the human voice) Pitch, perception of frequencies of sounds; the higher the frequency the higher the perceived pitch. Amplitude, the size of the waveform; in sound, this corresponds to the loudness of the sound and measurement is indicated in decibels (db), the sound pressure of a source when compared to a standard intensity of 10^-12 watts. Complexity, the number of different wave frequencies contained in a sound; in sound this, this corresponds to timbre.
