Is there a maximum difference between frequencies?
Question
May 10, 2010
I would like to know if there is a maximum difference between two frequencies where beat can be produced.

Answer
The beat frequency is an envelope of changes in amplitude that you hear or can be displayed on an oscilloscope. When the difference becomes an harmonic or multiple of the original frequencies, it becomes difficult to distinguish the beat frequency from the other frequencies. But still, there are beats being produced.
Thus, the maximum difference would depend on whether a could distinguish the beats.
