H2-21. Audible Young's Experiment - Group Listening
Purpose
To demonstrate interference of sound with two coherent sound sources.
Equipment
Loudspeakers on rotating boom permanently mounted on oscillator-amplifier.

Description
The oscillator-amplifier is set to approximately 3000 Hz, with identical signals being applied to both loudspeakers. Rotating the loudspeakers past the listeners allows them to observe the interference pattern by hearing the alternating maxima and minima in the intensity pattern.
