Two adjacent sound sources each emit a frequency of 527[Hz] in air, where the velocity of sound is 349[m/s]. How much further back would source one have to move so that an observer in front of the two sources would hear no sound?© BrainMass Inc. brainmass.com October 9, 2019, 10:15 pm ad1c9bdddf
wavelength = V/f
= 0.662 ...
Two sound waves of the same frequency arriving at a point with the path difference of half wavelength undergo destructive interference.
