On resonance, releasing sound reduces its loudness

Evidence

Trumpets rely on resonance, and resonance relies on reflection and confinement. In the absence of friction and dissipation, there is no contest: on resonance letting out the sound is self-defeating and makes it less loud (a trumpet is played on resonance). — Eric J. Heller, Why You Hear What You Hear- An…, 1513
