PURPOSE: To demonstrate the resonance behavior of a Helmholtz resonator.
DESCRIPTION: The Helmholtz resonator is excited by an oscillator driving a small loudspeaker. Resonances in the system are sensed using a sound probe inserted into a nipple on the resonator, and displayed on the oscilloscope.
REFERENCES: (PIRA 3D30.40)
EQUIPMENT: Helmholtz resonator, loudspeaker, and sound probe mounted on optical rail, mic amplifier, oscillator, oscilloscope.
SETUP TIME: 10 min.
