The Interference in Time and Beats JavaScript Model simultaneously plays two sounds with frequency fA and fB and displays the signal recorded by a nearby microphone on an oscilloscope display. The oscilloscope's horizontal time axis is shown in seconds and the drop-down menu sets the scale. The vertical axis shows the sound amplitude for each sound and the sum of the sounds depending on the check-box settings.

The Interference in Time and Beats JavaScript Model was developed using the Easy Java Simulations (EJS) version 5.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.
