The effect of envelope on fusion of tones with inharmonic partials
Elizabeth A. Cohen · The Journal of the Acoustical Society of America · 1979
Temporal envelopes for tones with an inharmonic partial structure were generated using the Systems Concepts Digital synthesizer. [E. Cohen, J. Acoust. Soc. Am. Suppl. 1, 65, S123(A) (1979)]. The reasons for choosing envelopes based on musical viability rather than a flat “psychoacoustically standard” pattern, will be discussed. Subjects were asked to make judgments on the degree of tone dispersion for single tones differing in degree of inharmonicity and temporal envelope. The importance of attack and decay times, as well as transients in the signal will be explained. A real-time experiment on the determination of subjective interval size of dyads using two different envelope patterns also revealed that duration of the “steady state” portion of signal has an effect on tone fusion.
