Two speakers are in-phase, and you are standing in front of them. Using a measuring tape, you see that one is 3.5 meters away, and the other is 3 meters away. If the speed of sound is 332 m/s and the speakers are emitting at 1328 Hertz, what is the phasing of the sound you hear? In Phase Out-of-phase, can't hear a thing... Out-of-phase, here it slightly, more out-of-phase than in-phase Out-of-phase, but hear it pretty well - more in-phase than out-of-phase
