PSC 136 Lecture Notes - Lecture 7: Musical Tone, Fundamental Frequency, Missing Fundamental
Document Summary
Each of the mechanisms can be considered in terms of several properties. Survival value of the associated brain function. Music arises from sequences of auditory objects. All sounds (and all signals) can be broken down into constituent frequencies. Frequency - the rate at which something occurs or is repeated over a particular period of time. Pure tone - a sound consisting of a single frequency (sine wave) Pitch - the quality of a sound governed by the rate of vibrations producing it; the. Definition of a sinusoid (pure tone) degree of highness or lowness of a tone. X(t) = a sin (2 / + ) A=amplitude, t = period, = starting phase. The height of the dashed line y indicates the amplitude of the waveform. The interval from 0 to t indicates the period of the waveform. Complex tone - a sound consisting of multiple frequencies, typically harmonics of a fundamental frequency.
