Frequently sound is described using terms such as pitch, tone, frequency, intensity or loudness. To understand the origins of these terms as well as to understand the mathematical models used to represent sound, this applet can help you to explore the dynamics of a sound wave.
The sound wave is controlled by two parameters: the amount of initial energy put into the string (initial displacement) and the amount of tension in the string.
Use the sliders to adjust these parameters:
Use the applet to simulate various sounds.
