Question:
Suppose a spherical loudspeaker emits sound isotropically at 10 W into a room with completely absorbent walls, floor, and ceiling (an anechoic chamber).
(a) What is the intensity of the sound at distance d = 3.0 m from the center of the source?
(b) What is the ratio of the wave amplitude at d = 4.0 m to that at d = 3.0 m?
