Two loudspeakers, A and B (Fig. 16.41), are driven by the
same amplifier and emit sinusoidal waves in phase. Speaker Bis
2.00 m to the right of speaker A. The frequency of the soundwaves
produced by the loudspeakers is 206 Hz. Consider point Pbetween
the speakers and along the line connecting them, a distance x tothe
right of speaker A. Both speakers emit sound waves thattravel
directly from the speaker to point P. a) For what values of xwill
destructive interference occur at point P? b) For what values ofx
will constructive interference occur at point P? c)Interference
effects like those in parts (a) and (b) are almost never a factorin lis-
tening to home stereo equipment. Why not?
