Sound scattering, not tuning, explains voice enhancement from vessels

Evidence

The reflection mechanism mentioned by Mersenne is not dependent on the tuning of the vessel, in contradiction to the claims made by Vitruvius. Nonetheless, Mersenne is apparently saying the voices are “stronger and more clearly understandable” even without the resonance mechanism being in effect. This might be true just from the scattering of sound waves from the outside of large vessels. — Eric J. Heller, Why You Hear What You Hear- An…, 1260
