Chapter 17, Problem 17.105(choose chapter or problem)
The three identical loudspeakers in FIGURE P17.71 play a 170 Hz tone in a room where the speed of sound is 340 m/s. You are standing 4.0 m in front of the middle speaker. At this point, the amplitude of the wave from each speaker is a. a. What is the amplitude at this point? b. How far must speaker 2 be moved to the left to produce a maximum amplitude at the point where you are standing? c. When the amplitude is maximum, by what factor is the sound intensity greater than the sound intensity from a single speaker?
