Can the energy in two waves cancel out? If so, why?

WebFor example, if two complete cycles of high and low volumes are heard every second, the beat frequency is 2 Hz. The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz ...

The other part is a cosine wave which oscillates with the difference frequency f = ½(f 1 - f 2). This term controls the amplitude "envelope" of the wave and causes the perception of "beats".
