摘要:
Envelope‐induced pitch shifts were measured for exponentially decaying complex tones consisting of two sinusoidal components with frequencies f 1=n f 0+50 Hz and f 2=(n+1) f 0+50 Hz, wherenequals 3, 4, or 5 and exponential decay rates were 0, 0.5, 1, and 2 dB/ms. Four subjects adjusted a sinusoidal comparison tone to match the virtual pitch of the (missing) fundamental and the pitches of the lower and upper partials f 1and f 2. Pitch shifts for f 1are generally less, and pitch shifts for f 2always greater, than envelope‐induced shifts observed in isolated sinusoidal tones of comparable frequency and envelope decay rate. Pitch‐shift functions for virtual pitch are similar in magnitude and shape to average pitch‐shift functions of the partials, which supports the idea that virtual pitch depends on spectral pitch.
