Steady state emission depends on power supply, not internal stored energy
Evidence
In fact, the extra energy and pressure inside the trumpet on resonance is not a sufficient argument, since once the trumpet is “filled up” and in the steady state (after maybe 0.06 second) then neglecting friction all the power being supplied is coming out as emitted sound. Once your bathtub is full, the rate at which water spills over has everything to do with how fast the faucet is running, and nothing to do with how much water the tub holds—if there are no other leaks! The “other leaks” become the central issue. — Eric J. Heller, Why You Hear What You Hear- An…, 1524
