WAVES BEATS: INTERFERENCE IN TIME Beats is an example of the interference of two waves in the time domain. Loud-soft-loud modulations of intensity are produced when waves of slightly different frequencies are superimposed. Consider two sound sources producing audible sinusoidal waves at slightly different frequencies and . How can a piano tuner use beats in tuning a piano? What will the person hear? If the two waves at first are in phase they will interfere constructively and a large amplitude resultant wave occurs which will give a loud sound. As time passes, the two waves become progressively out of phase until they interfere destructively and the sound will be
