BTW, 120 db SPL is also around 1 W / m^2, so
harvesting energy from
sound panels (similar to solar panels) is another idea that won't
go far.
I like your wording here:-)
Purely accidental - 'pun not intended'.
Especially considering the fact that sound
distributes spherical. So the energy looses in r^3... afair.
No, sound power (for a point source) goes down as the square
of distance. It's power / surface and the surface of a sphere
is 4 * pi * r^2.
