Repetition pitch is computable by pure geometry of direct and bounce paths

Evidence

Listen carefully for the presence of a 200 Hz sinusoidal partial with only partials 400, 600, 800, 1000, 1200, and 1400 present. You won’t hear a 200 Hz partial at low sound intensities, yet a 200 Hz pitch will prevail. The 200 Hz partial is not there in the original sound, nor is it created for us by any part of the hearing system from the outer ear to the auditory cortex. What is created by that system is the sensation we call pitch. Pitch is not partial. — Eric J. Heller, Why You Hear What You Hear- An…, 2031 (#exemplifies, via linked claim)
