 The frequency of the '​beats'​ tone that you hear is equal to the difference between the two other frequencies being played. If the frequencies are sufficiently close, you may not hear any beats at all, and if they'​re too far apart the beats will have a high enough frequency to be heard as a [[wp>​combination tone]]. The frequency of the '​beats'​ tone that you hear is equal to the difference between the two other frequencies being played.
