Question

(b) Consider the speaker set-up in the previous question. Each speaker emits a frequency of 6.6 · 10^2 Hz in phase with the other. The listener is seated directly in front of one speaker, 1.6 m away. The speakers are 2.4 m away from each other. How many extra wavelengths are needed for sound to get from speaker 2 to the listener? Take the speed of sound in air to be 3.4 · 10^2 m/s. Extra wavelengths |x1 - x2| / ?: (c) What kind of interference, if any, does the listener in the previous question experience? There is not enough information to tell Destructive interference Constructive interference No interference
