n Two vibrations of slightly different frequencies f1 and f2 when added together, produce in a detector sensitive to both these frequencies, a regularly varying response which rises and falls at the “beat” frequency fb = [f1f2]. It is important to note that a resonator which is sharply tuned to fb alone will not resound at all in the presence of these two beating frequencies. See  Combination Frequencies.
