Two speakers are separated by two meters in a plane. They are in-phase. They project 891 Hz sound waves. The speed of sound is 343 m/s.

Consider the point 5.0 m in front of one of the speakers, perpendicular to the plane of the speakers. At this point, is there maximum constructive interference, perfect destructive interference, or something in between?

    1. (10 points) Two identical speakers are continuously emitting sound waves uniformly in all directions at 440 Hz. The speed of sound is 344 m/s. Point P is a distance of r = 3.13 m away from speaker 1 and r2 = 4.30m from speaker 2: i. What is the phase difference between the waves at Point P? ii. Is this a point of constructive interference, destructive interference, or something in between? Explain.

    This experiment requires two speakers that can be separated by some distance (try 1-2 meters). Try playing a single frequency using a tone generator and walk side to side in front of the speakers. Can you hear where there is constructive and destructive interference? Can you predict where the sound will get louder or quieter? What changes when you change the frequency?
