How does Dynamat stop road noise?
As a car operates, it generates noise. This noise is caused by the transference of energy (vibration) from the internal components and from the road to the chassis of the vehicle. The chassis (doors, floors, roof etc.) transforms this vibration into audible noise. Dynamat transforms the energy (vibration) into silent energy.
