In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, explore the characteristics and behavior of sound waves. Begin by varying the frequency and amplitude of the sound waves to hear how the sound changes. Other options allow you to experiment with properties of multiple sound waves—created by two sources or by reflection—to demonstrate constructive and destructive interference. You can also hear how sound waves are affected by changing air pressure.
