Helmholtz resonator is described by a cavity of air with an opening which resonates at a natural frequency when the air is excited. The relationship of the resonate frequency to the volume of the cavity and size of the port.
- To study acoustic cavity resonators and determine their characteristic frequency.
- To study the dependence of characteristic frequency on the volume of cavity of the resonator.
- Easy setup.
- Quick measurement.
- Computer based data collection.
- FFT analysis
