Question

Quizplus · Accepted Answer

In order for two sound waves to produce audible beats, they must have slightly different frequencies. The beats are produced because the waves interfere with each other constructively and destructively, creating alternating areas of reinforcement and cancellation. This causes the overall amplitude of the sound to increase and decrease, resulting in the perception of a "beat" frequency.
