Homework Help: Physics

Posted by Mary on Friday, April 27, 2007 at 10:42am.

A recording engineer works in a soundproofed room that is 47.5 dB quieter than the outside. If the sound intensity in the room is 1.40 x 10^-10 W/m2, what is the intensity outside?


-47.5=10log( 1.40 x 10^-10/Io
divid each side by ten, then the antilog of each side, and solve.
