Why don't we experience beats in case of superposition of two sound waves with a large difference in their frequencies?
(N/A) Beats are the periodic variations in the intensity of sound heard when two sound waves of slightly different frequencies superimpose on each other. The human ear has a phenomenon known as the persistence of hearing,which limits our ability to distinguish individual sound pulses. We can only perceive intensity variations up to a maximum of $10$ beats per second. If the difference in frequencies is greater than $10 \ Hz$,the pulses follow each other so rapidly that the ear perceives a continuous sound rather than distinct beats.
