Well as for 'distance law'. Microphone receives and registers sound
pressure instead of sound intensity.
intensity != pressure
intensity ~ pressure^2
While true that energy at 2x distance is 1/4, the pressure excerted is
1/2 neverheless (pressure value is independent of area - i.e. it uses
constant nominal area).
So you end up with a linear correlation instead of square one.
pressure ~ 1/distance
intensity ~ 1/distance^2
There is also the thing with acoustic impendance. For simplicity I
didn't include it into "equations" and that's the reason they're not
equalities, but are proportionalities.
