Technical Specifications Vibration Damping Tile SOUNDOWN Vibration Damping Tiles SOUNDOWN Vibration Damping Tiles are an easily applied damping layer for stopping reverberant “ringing” vibration in heavy plate constructions. Structural damping material consumes vibrational energy and transforms it into heat. It dissipates vibrational energy in the structure before it can build up and radiate as sound. Substrates upon which the tiles are commonly installed include: steel, aluminum, and fiberglass laminate. Vibration damping loss factor (n), at 1,000 Hz for the 3/8" tile, exceeds 0.10 on aluminum plate up to 0.40". Even greater damping values are obtained when the material is installed as a "constrained layer" treatment as shown on the bottom diagram to the left. Damping Material Base Layer Damping tiles and sheets are a polymeric product resistant to fuel, water, and fire. The product is optimized for use in the temperature range of 55° to 90° F. All product configurations pass UL-94V and ASTM D-635 flame testing. Above: a free-layer damping application.This is the most common and easiest form of damping.The vibrational energy is dissipated due to the extension and compression of the damping material due to the vibrational stress of the base layer. Adhesive Constraining Layer Damping Layer Base Layer (Substrate) Above: a constrained-layer damping application. During vibrational distortion the system flexes creating sheer forces on the constraining layer. It is these sheer forces that causes the energy to dissipate and turn into heat. These damping materials are bonded to the treated structure using 100 percent solid epoxy systems such as the TA-30 resin supplied by Soundown Corp. Our 1/16", 1/8" and 1/4" damping material can also be supplied with pressure sensitive adhesive (PSA) for use on thinner substrates. Typical shipboard applications include: Hull plating (above props or areas affected by wave actions) Tank Tops Decks or Bulkheads (esp in close proximity to machinery) Walking Decks Stair Treads Thruster Tunnels and adjacent areas
