Time-delayed repetition of sound produces a matching repetition pitch

Evidence

Figure 21.4 Autocorrelation function c(τ) of the sound trace with repetition at 5 ms. According to the autocorrelation theory of pitch perception (chapter 23), we should hear a 200 Hz repetition pitch, and this is just what happens. — Eric J. Heller, Why You Hear What You Hear- An…, 1935

Category: Factual Claims

• CANDY: A 5 ms echo of white noise yields a 200 Hz pitch — a compact, surprising auditory illusion explainable in one breath.
