Suppose that in Conceptual Example 8 (see Figure 16.24) the person is producing 1.1 mW of sound power. Some of the sound is reflected from the floor and ceiling. The intensity of this reflected sound at a distance of 3.0 m from the source is 4.4 × 10-6 W/m2. What is the total sound intensity due to both the direct and reflected sounds, at this point?
