Two loudspeakers are placed d = 3 m apart and facing the same direction. The loudspeaker diaphragms are vibrating in phase with each other, producing a single frequency sound with a wavelength of A1.2 m. (a) Determine approximately the distance between the points on the wall on the right where the sound will be the loudest. loudspeakers X 4.5 m (b) Suppose there were only the speaker at y = 1.5m, and there was a perfectly reflecting wall along y = 0. Given that the sound reflected off the wall undergoes a phase change of radians, where will the maxima and minima of the interference pattern be heard? Justify your answer. (c) Why are no interference effects usually heard with speakers in a typical living room? Two loudspeakers are placed d = 3 m apart and facing the same direction.
