Beats and Standing Waves In Problem, suppose the observer walks toward one speaker with a speed of 1.35 m/s. (a) What frequency does the observer hear from each speaker? (b) What beat frequency does the observer hear? (c) How far must the observer walk to go from one point of constructive interference to the next? (d) How many times per second does the observer hear maximum loudness from the speakers? Compare your result with the beat frequency from part (b).
Problem
Two loudspeakers are placed at either end of a gymnasium both pointing toward the center of the gym and equidistant from it. The speakers emit 266-Hz sound that is in phase. An observer at the center of the gym experiences constructive interférence. How far toward either speaker must the observer walk to first experience destructive interference?
