Sound Intensity and Power

At a distance of 3.8 m from a siren, the sound intensity is 3.6 x 10^-2 W/m^2. Assuming that the siren radiates sound uniformly in all directions, how do you find the total power radiated?

Solution Preview

The intensity of a sound wave is its power/unit area.

I = P / A

Now the ...

Solution Summary
