Why your ears perceive a pulsing rhythm from two steady tones
In short: Have you ever wondered how two different musical notes can create a single, rhythmic thumping sound? This video explains the physics of beats, showing how wave interference transforms simple frequencies into complex patterns.
Beats occur when two waves with similar frequencies overlap. As these waves travel together, they undergo constructive and destructive interference, causing the amplitude—or volume—to fluctuate periodically.
The specific frequency of the resulting beat is determined by the difference between the two original wave frequencies. This phenomenon demonstrates how our perception of sound is shaped by the underlying mechanics of wave physics.
