Science Buddies: Beats

Systematically explore different frequency combinations in this experiment provided by Science Buddies. You will use your computer to create sound files to play pure tones on your computer, one frequency in the left channel, and another in the right channel, discovering if different frequency combinations result in different beats. Then using a second device, you will record the sounds of the left and right speaker separately, and then both speakers together. Using sound editing software you will then examine and analyze the recorded files.
