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.

What you can learn about

  • Cavity resonator
  • Resonance frequency
  • Acoustic resonant circuit

Operating system-independent software included. Computer not provided.
