They are synchronized such that when one of the speakers is creating a pressure maximum in the air, the other is not causing any air particle displacement from the equilibrium position. What effect does this synchronization have on the sound heard from the speakers together? There is no sound heard due to total destructive interference. There is a louder sound heard due to total constructive interference There is no way to tell from the information given whether it is (a) or (b), but it must be one of those. The sound heard will be the same volume as is heard from an individual speaker. Beats will be heard. MC 5 a. b. c. d. e.

Explanation / Answer
