Loudspeakers A and B are 7.00 m apart and vibrate in phase at 172 Hz. They radiate sound uniformly in all directions. Their acoustic power outputs are 0.0008 W and 0.0006 W, respectively. The air temperature is 20 C.
(a) Determine the difference in phase of the two signals at a point C along the line joining A and B, 3.00 m from B and 4.00 m from A.
(b) Determine the intensity ad sound intensity level at C from speaker A alone (with B turned off) and from speaker B alone ( with A turned off).
(c) Determine the intensity level at C from both speakers together.
