"When two pure tones of slightly different frequency are superposed,
our ears perceive audible beats at a rate given by the difference of
the two frequencies."

"When two tones are sounded together, a tone of lower frequency is
frequently heard. Such a tone is called a combination tone.  The most
commonly heard combination tone occurs at a frequency f2 - f1."
