I'm not really sure what you're talking about, but your math blows. 3'3" = 39". 39^2 = 1521. 1521" / (12" / 1') = 126'. Things are easier if you use metric...

actually, you better watch out there because I think what you meant was:
39^2 sq. in. = 1521/(144sq"/sq') = 10.5625 sq ft. (i.e. 3.25^2 sq ft)

but yeah, the original post made little sense. and of course, both sound and EM waves drop off as r^2. (think surface area)
