Demos: 4B-12 Interference of Sound

This demonstration gives audible effects of constructive and destructive interference. With two speakers set approximately 60 centimeters apart and amplified, students throughout the lecture hall can hear louder or softer tones. Students will only need to move their heads a few centimeters to hear the difference. It might help to have students cover one ear to better hear the difference in sound.
