Delayed identical sound reproduces a pitch whose frequency equals the inverse delay

Evidence

The pitch is equivalent to a sound whose f0 is equal to (1/delay), and the effect works for delays between approximately 1 ms and 10 ms depending on the listener, giving an equivalent f0 range for the effect of 100 to 1000 Hz. With modern electronic equipment it is quite possible to play tunes using this effect! — David Howard, Jamie Angus, coustics and Psychoacoustics, 941
