The location of the speakers in this problem is what's throwing me off.
Two speakers, one directly behind the other, are each generating a 245-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? The speed of sound is 343 m/s.© BrainMass Inc. brainmass.com October 9, 2019, 8:41 pm ad1c9bdddf
Calculations to find the smallest separation distance between speakers for destructive interference is given as both a Word document and PDF.
