Abstract
The experimental observation of the pressure in the cavity of a 2-D sonic crystal is presented. The sonic crystal consists of the polymethyl methacrylate cylinders in air background. The full band gap and defect mode are demonstrated experimentally and compared with the calculating results. The spectra in the cavity are measured for different sizes of the sonic crystal. The pressure in the cavity and quality factor of the cavity can be enhanced as the sonic crystal is enclosed by the cylinders. The numerical results are confirmed by the experiment.
