[sdiy] Total acoustic energy of an object

When using a bow, a horn, a guitar body, or another acoustic
instrument, when the object emits sound waves its integrity is
diminished in tiny amounts. Eventually it would get destroyed.

Similarly to total energy that can be released by burning matter in
oxygen, or total energy released when an item drops on the ground, Is
there some form of "total acoustic output" that can happen over the
lifetime of an object? How would you define it, theoretically?

One can imagine that forced vibration has a different effect to free vibration.
