Impulse energy is fixed at impact regardless of later echoes
Evidence
When sounds destructively interfere with each other, they do not disappear. Instead, they travel through each other. Similarly, when they constructively interfere, they do not grow but simply pass through each other. This is because although the total pressure, or velocity component, may lie anywhere between zero and the sum of the individual pressures or velocities, the energy flow of the sound waves is still preserved, and so the waves continue to propagate. — David M.
