Dynamat is a thin, flexible, easy to cut and mold sheet that actually stops noise causing resonance and vibration:
As a car operates, it generates noise. This noise is caused by the 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 vibration into silent energy.
Even a small amount of Dynamat can cause a profound noise reduction. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB. Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18dB.
- A bottom layer of 1/8" neoprene foam that damps the material it is mounted against and decouples the vibrating panel from the other layers of material
- 15 mils of acoustic lead, the ultimate low-frequency barrier that not only provides strong low-frequency attenuation, but also enables Extremeliner to conform to irregular or uneven surfaces
- 1/4" of high-efficiency, open/closed cell acoustic foam optimized for absorbing low-frequency sound. The open cells are designed to accept sound waves while the closed cells dissipate them
- A 3 mil urethane top facing with a random pattern for a tough outer coating that minimizes reflections and dramatically improves system performance, especially in the lower mid-range and mid-bass frequencies where normal acoustic foam becomes less effective
