Vehicle acoustic damping and decoupling system

A vehicle acoustical system for attachment over a vehicle interior sheet metal component, comprising:

• a carpet layer;
• a sound barrier layer secured to the carpet layer;
• and
• a bubble pack comprising a first film layer and a second film layer secured to the first film layer, said first and second film layers cooperating to form a plurality of pockets therebetween, said pockets comprising a gas disposed therein such that the pockets are substantially compressible, said pockets including not more than approximately 25% by volume kinetic energy dissipating granules so that the granules only partially fill the pockets to maintain said compressibility to allow decoupling of the sound barrier layer from the sheet metal for improved isolation of noise, and wherein said bubble pack is adapted to be positioned in direct contact with the sheet metal component.
