Beating

Beating is a phenomenon that occurs when periodic waves are combined, resulting in [amplitude] fluctuations.

When summed, two periodic waves with slightly different frequencies exhibit a periodic change in [phase] relationship, resulting in amplitude fluctuations.

• in [sound waves], when the difference in [frequency] between two waves exceeds 20 Hz, it transitions to become two audible tones
