Destructive Interference (Phase Cancellation): A phenomenon that occurs when speakers are 180 degrees out of phase, i.e., what one speaker is trying to produce, the other speaker is fighting to cancel. One speaker's wave is in the positive phase (rarefaction), while the other speaker's wave is in the negative phase (compression).

Destructive Interference: When the peaks of one wave match the troughs of another, the waves interfere destructively. The amplitudes of the interfering waves cancel to give the resultant wave a lower amplitude.

Constructive Interference: When the peaks and troughs of two interfering waves match, the amplitudes add to give the resultant wave a higher amplitude.
