Repetition pitch equals the reciprocal of the echo delay time

Evidence

The perceived pitch f is given by the reciprocal of the delay time τ, f = 1/τ. If there is a 0.01 second delay of the bounced sound, a 100 Hz pitch can be heard, which, however, is far from being a musical tone. — Eric J. Heller, Why You Hear What You Hear- An…, 2146
