At a distance of 3.2 m from a siren, the sound intensity is 3.2010-2 W/m2. Assuming that the siren radiates sound uniformly in alldirections, find the total power radiated.

A popular car stereo has four speakers, each rated at 60 W. In answering the following questions, assume that the speakers produce sound at their maximum power.

A)   Find the intensity I of the sound waves produced by one 60-W speaker at a distance of 1.0 m.

B) Find the intensity I of the sound waves produced by one 60-W speaker at a distance of 1.5 m.

C) Find the intensity I of the sound waves produced by four 60-W speakers as heard by the driver. Assume that the driver is located 1.0 m from each of the two front speakers and 1.5 m from each of the two rear speakers.

D)The threshold of hearing is defined as the minimum discernible intensity of the sound. It is approximately 10^(-12) W/m2. Find the distance, d from the car at which the sound from the stereo can still be discerned. Assume that the windows are rolled down and that each speaker actually produces 0.06 W of sound, as suggested in the last follow-up comment.
