Asked by WINNY
Two loudspeakers are placed above and below each other, as shown in the diagram below. The
speakers are driven at a frequency of 4.50 * 10^2 Hz by the same source. An observer is in front of the
speakers (to the right) at point O, at the same distance from each speaker. What minimum vertical
distance upward should the top speaker be moved to create destructive interference at point O? The
speed of sound is 343 m/s.

I am wondering how high the speakers ears are. You can't calculate the difference in distances from bottom and top without that.
