H3-41: RESONANCE CURVE - HELMHOLTZ RESONATOR

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.

SUGGESTIONS:

REFERENCES: (PIRA 3D30.40)

EQUIPMENT: Helmholtz resonator, loudspeaker, and sound probe mounted on optical rail, mic amplifier, oscillator, oscilloscope.

SETUP TIME: 10 min.
