Abstract
We study experimentally the spectral statistics of acoustic resonances in quartz blocks. About 1400 well resolved resonances are measured. T he short range fluctuations are well described by random matrix theory . The properties of quartz allow us to measure the gradual breaking of a point-group symmetry. This is statistically fully equivalent to the breaking of a symmetrylike parity or isospin in a quantum system.
