Abstract: | The duration sensation of bandpass noise was examined while changing the factors (τ1, φ1and τe) extracted from the autocorrelation function. The white noise and bandpass noises with six center frequencies (125, 250, 500, 1000, 2000 and 4000 Hz) with different bandwidths were used as stimuli. A paired-comparison test comparing the white-noise duration with bandpass-noise duration was conducted under the conditions of constant sound pressure level (SPL; 80 dB(A)) and rise and fall times (1 ms). Results indicate that the duration of bandpass noise is judged to be longer than that of the white noise. The duration sensation of the bandpass stimuli with longer τ1is significantly longer than that of the stimuli with shorterτ1 (p<0·01). |
