In the figure below, two speakers separated by distance d1=3.0 m are in phase. Assume the amplitudes of the sound waves from the speakers are approximately the same at the listener's ear at distance d2=7.1 m directly in front of one speaker. Consider the full audible range for normal hearing, 20 Hz to 20 kHz. What is the lowest frequency that gives completely constructive interference at the listener's ear. consider the speed of sound 343 m/s di Speakers Listener
