Abstract

A baffle is provided that includes a body portion having a first layer and a second layer defining a free space therebetween. A sealer is disposed on the body portion in the space between the first layer and the second layer. The space has a predetermined volume and the sealer is expandable in the space. When placed in a cavity, such as a vehicle cavity, the sealer also expands into the cavity to seal the cavity. The baffle is more light-weight and capable of reducing noise and vibration, especially at higher frequencies than traditional baffles.
