Suppose that a person singing in the shower is producing1.34 mW of sound power. Some of the soundis reflected from the floor and ceiling. The intensity of this reflected sound at a distance of 3.01 mfrom the source is 4.40 10-6 W/m2. What is the total sound intensitydue to both the direct and reflected sounds, at this point? Assumethat the sound is spherically symmetric.
