A.) Two loudspeakers are separated by a distance of 6.2 m. A
listener sits directly in front of one speaker at a distance of 6.4
m so that the two speakers and the listener form a right triangle.
Find the lowest frequency for which the path difference from the
speakers to the listener is an odd number of half-wavelengths.
Assume the speed of sound is 340 m/s.
B.) Find the second lowest frequency for which the path difference
from the speakers to the listener is an odd number of
half-wavelengths.

In the figure, two loudspeakers, separated by a distance of d1 = 2.89 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of a listener, who is d2 = 4.08 m directly in front of one of the speakers. Consider the audible range for normal hearing, 20 Hz to 20 kHz. (a) What is the lowest frequency that gives the minimum signal (destructive interference) at the listener's ear? (b)...

Two in-phase loudspeakers are placed along a wall and are
separated by a distance of 6.00 m. They emit sound (take vs = 343
m/s) with a frequency of 137.2 Hz. A person is standing away from
the wall, in front of one of the loudspeakers. What is the closest
distance x from the speaker the person can stand and hear a sound
intensity maximum?
