“Tone‐pips” were produced by brief rectangular electrical pulses being delivered through two sound‐effects filters in cascade with both high and low cut‐offs set at 2000 cps. Nearly all of the acoustic energy of the final signal was found to be concentrated in a band about an octave wide and centering at 2000 cps. The pulsing frequency was varied independently between 90 and 150 pips per second. Listeners describe the resulting sound as a “metallic buzz.” Listeners vary greatly in their ability to identify the two “pitches” present in this sound and in the accuracy with which they match with a pure tone either the pulsing frequency (about 130 per second) or the band‐pass frequency (2000 cps in the present series). Errors of exactly one octave are particularly common. In the theoretical discussion we argue that the “pitch” of a pure tone is a double attribute compounded of “buzz” (correlated with frequency of volleys of nerve impulses) and “body” (correlated with position of maximum stimulation on the basilar membrane).
