BTW, now that we're talking about power and energy in the musical,
acoustical sense, take a look at how much acoustical energy most
speakers radiate. Even the biggest ones.
A well tuned line array typically has .001 to .02 power conversion
efficiency from electricity to acoustics. Most of its power also
radiates away from its intended target. As a result, what you hear in a
concert is mere milliwatts of acoustic power. Of those, some land on
your ears; there a mere .05mW over the tympani membrane is deafening.
Just sayin, us DSP folks typically don't know where the physical limits
lie. Because we mostly deal with just numbers, we don't instantly see
where the physical restraints on amplitude are, nor the rest of the
psychoacoustics.
As such, I'd encourage people to do what e.g. RBJ just did: find the
absolute limits first, and then calibrate/scale their work based on
that. Because that way our DSP-sport ain't just about abject numbers
anymore; it has something to do with the real world as well. Its
numerics, its physical acoustical counterparts, and whatnot. :)
