Number of Pulses Required for Minimal Pitch
Irwin W. Pollack · The Journal of the Acoustical Society of America · 1967
The number of pulses required for minimal pitch was determined. For pulse intervals longer than 1 msec, appromixately a constant number of pulses is required: about three. For pulse intervals shorter than 1 msec. approximately a constant duration is required, about 3 msec. The results are in close agreement with findings for the click pitch of pure tones.
