Echoed sounds spaced 1-10 ms generate a perceived pitch of 100-1000 Hz

Evidence

When we listen to a note played on a musical instrument and we perceive it as having a clear unambiguous musical pitch, this is because that instrument produces an acoustic pressure wave which repeats regularly. … Each section that repeats is known as a “cycle” and the time for which each cycle lasts is known as the “fundamental period” or “period” of the waveform. The number of cycles which occur in one second gives the fundamental frequency of the note in hertz (or Hz). The fundamental frequency is often notated as “f0”, pronounced “F zero” or “F nought”, a practice which will be used throughout the rest of this book. — David Howard, Jamie Angus, coustics and Psychoacoustics, 774 (#complicates, via linked claim)

In each case, the highest common factor of the components is f0. This method also provides a basis for understanding how a pitch is perceived for non-harmonic sounds, such as bells or chime bars, whose components are not exact harmonics (integer multipliers) of the resulting f0. — David Howard, Jamie Angus, coustics and Psychoacoustics, 864 (#complicates, via linked claim)
