    • Abstract
  • Some experiments indicates that sonic crystals contain local resonant structures which is important for noise and viberation control. The effects of structural parameters on sound transmission loss of three-component sonic crystals are analyzed in this paper. The results indicates that in a certain frequency range,the higher the filling rate,the larger the sound transmission loss,and in low frequency range,there is no relationship between topological structure and sound transmission loss.
