A modified honeycomb panel with improved bonding technique is presented in this paper. The idea is to keep the basic mechanical properties of a honeycomb panel while to eliminate the coincidence phenomenon of the whole system by using modified bonding technique. A specimen was made and measurement was performed. Results show that the coincidence phenomenon of the whole system disappears and the weighted intensity sound reduction index is 4 dB higher than that of the corresponding honeycomb panel with similar surface density and static strength.
