When two sound sources produce identical waves you might expect to hear a sound twice as loud. The situation is somewhat more complicated
IDENTICAL WAVES IN PHASEIDENTICAL WAVES 162° OUT OF PHASE
IDENTICAL WAVES 18O° OUT OF PHASE
In the next example, two of waves of slightly different frequency interact to form a distinctive pattern called "beats". To clearly illustrate this process, different pictures represent different proportions of the total time you hear. The amount of each tone shown is indicated by a percent. of the total time.
