摘 要：In the experiment we have measured the resonant frequencies of perforated sheets with perforation rates from 0.008 to 0.30. Compared those frequencies with the corresponding resonant frequencies of homogeneous, or un-perforated one we obtained an empirical relationship between the resonant frequency and perforation rate, which can be used for industrial purpose. We have also studied the change of vibrational energy distribution of perforated sheet related to that of homogeneous.
