Sound Trap™ laminated steel comprises two steel skins, constrained over a layer of viscoelastic material, which is said to absorb vibrational energy and reduce noise in end products. This material is currently used on major appliances such as washers and dryers, breadmakers, air-conditioners, and a new line of Briggs & Stratton IC engines. Sound Trap material acts as a noise and vibration-reducing component when used as the enclosure, inner shell, compressor mounting plate, or other housing structure. The material can reportedly be formed or welded with no loss of performance integrity and no delamination.
