The effective damping of structure-borne sound is a major issue in lightweight automotive body construction. Today, there are two solutions — damping pads or Liquid Applied Sound Deadening products. The major difference is the manual application of damping pads versus efficient robotic method of LASD.
Manually applied damping pads require extensive inventories, on-line labor and create house-keeping concerns in the paint-shop. Additionally, effective attachment of damping pads to vehicle overhead and vertical surfaces require magnetic inlays or adhesive bonding. By contrast, bulk application of LASD materials reduces complexity in assembly plants, and they adhere to overhead and vertical surfaces without need for additional parts.
