Don't phase me, bro! When two or more identical sound waves arrive to a listening source at slightly different times, it can result in what phenomenon?
Answer Phase cancellation
This is the reduction of energy that occurs when two waveforms that are opposite in polarity with one another start canceling each other out. The effect is a greatly reduced or eliminated volume. When two identical waveforms are completely out of phase (by 180 degrees), the result is a total silencing or cancellation of the signal.
