Abstract

A broadband sound shield based on layers of locally resonant sonic materials (LRSM) was demonstrated. Each resonating layer was found to vibrate similar to an independent unit. A broadband sound barrier significantly better than dictated by mass density law was achieved. The results show that the LRSM samples spacing between resonators is not a factor in determining the maximum attenuation frequency.
