Two loud speakers separated by a distance of 2.0 m are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of the listener, who is located 3.75 m directly in front of one of the speakers, such that the spea kers and the listener make a right angle triangle.
a. For what frequencies in the audible range (20 %u2010 20,000 Hz) does the listener hear a minimum signal?
b. For what frequencies is the signal a maximum?
