Principle

Acoustic cavity resonators possess a characteristic frequency which is determined by their geometrical form. In this case the resonator is excited to vibrations in its resonance frequency by background noise.

Benefits


Measure the resonance frequencies without additional excitation by using only the ambient noise

Immediate observation of both, the sound wave signal and the resonance frequencies using FFT

Measure live while changing the body volume and thus the resonance frequency

Simplified implementation: all pre-settings already prepared



Tasks

Determination of different resonance frequencies of a resonator depending on the volume.
