Suppose we have two haves with slightly different frequencies

The sum of these two waves will lead to interference in time  temporal interference

 

The cosine has one max and one minimum per cycle

Careful: Human ears hear them as two intensity maxima per cycle

 

 

 

// the number of beats per second, equal to the difference in the frequencies of two interacting tones or oscillations.
