Why sound deaden your vehicle?

• Reduce road, engine and wind noise
• Improves the acoustics inside your Van or Car
• Improves the overall comfort

When attempting to make a vehicle quieter and more comfortable to drive, there are 3 steps that are used:

The first step would be to use a sound deadening mat, which is designed to stop vibrations. Vibrations are caused in the vehicle from the engine, the tyres and general road noise; the metal panels inside and around the vehicle then resonate and are essentially amplified to a noise that you can hear. By applying a sound deadening mat to the metal; the vibrations will be dampened, and the vehicle will instantly seem quieter.

The second step is to absorb any airborne noise that is still present and coming through the doors, the floor, or the roof. A range of foam-based products are used to achieve this.

Closed cell foam has both the benefits of superb thermal insulation & acoustical absorption.

Wave diffusers might be used because they can absorb up to 40% more sound than plain material.

Foam materials are also great for preventing any plastic panels from rattling or squeaking.

The final step is to apply a MLV (mass loaded vinyl). This is designed to block and absorb any unwanted sound waves. This is recommended for use on the cabin floor, bulkhead and boot floor once the panels have been already treated with the sound deadening mat.
