what is the formula for beat frequency. The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. Thats just the beat frequency.
For example if two complete cycles of high and low volumes are heard every second the beat frequency is 2 Hz. Given parameters are f 1 550Hz and f 2 380Hz. Wave envelope for two tones.
For example if two complete cycles of high and low volumes are heard every second the beat frequency is 2 Hz.

The mathematical formula for the beat frequency can be derived from the expression for the superposition of the two original sine waves.
