Constrained layer dampning.....

216.176.7.228

is a very effective way of controlling vibration. I found out about it through talking to an engineer who specialized in acoustics. He used the same basic technic as yours. A sandwich of materials in which the speed of propogation of sound is different for the middle material. Same principle as Dynamat etc. Much more effective than a thicker wall or adding more internal sound absorbing material.
