Kimbo,
You may also want to consider a method of fragmenting the soundwaves by using soft, cast urethane pads with texture. These materials will fragment the soundwave without converting the sound energy into any other form (i.e. heat.
The material is not Dynamat. That product is an asphalt based vibration damping sheet material. The acrylic adhesive itself is an entirely different product all together. It does not damp vibration beacuse it does not have the mass nor the energy conversion caracteristics of viscoelastic damping...
You may want to consider a damped inter-layer wall construction. Using multiple layers of sheetrock will reduce the level of airborne sound energy simply because of the increased mass in front of the sound, however it's similiar to using a vibration dampers to reduce airborne sound, not the...
I am looking for a US manufacturer of thermal control compounds. Preferably a latex emulsion with glass microballoons for automotive and industrial applications. Any suggestions?
