Chrysler Group has launched the Durango 2004 model that has new noise control products in the body.
PUR foam is a patented noise suppression adhesive that is injected into the body of the vehicle to minimize noise, vibration and harshness (NVH). The second technology, Liquid Applied Sound Deadener system (LASD) is an underbody system that applies a liquid compound to the vehicle’s floor pan and helps reduce noise inside the vehicle.
