Resonance requires confinement of previously emitted amplitude

Evidence

Some kind of confinement and thus “storage,” or reflective return, of previously emitted amplitude is required; if the arriving amplitude simply rushes away never to return, there can be no resonance. — Eric J. Heller, Why You Hear What You Hear- An…, 908
