3D30.40 - Helmholtz Resonator
No preparation necessary other than occasional oiling of the variable resonator.
CAUTION: The glass resonators are very fragile!!
The Sea Shell is not a Helmholtz Resonator. The air volume of the shell will be exited at the shells resonant frequencies, of which there should be several. This shell has several resonances at frequencies below 300 Hz.
