# Sound Intensity and Power

Not what you're looking for?

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 Summary

This solution uses the equation for sound intensity and sphere to determine the total power radiated from the siren. All steps are shown with brief explanations.

##### Solution Preview

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

I = P / A

Now the ...
