Driving Noise

Step 1: Sealing Gaps

In old cars gaps occur due to aging. Every gap is a sound crack and it will ensure that air sound passes into the car. An example of a common sound crack is missing rubber around part of the car door. This is considerably improved by placing new rubber. You must ensure that there are no openings under the bonnet in the bulkhead that can operate as sound-cracks.

It is important that all gaps are sealed.

Step 2: Anti-drumming

When driving the wheel-arches and the rest of the car vibrates. These vibrations are audible as sound in the car. In order to stop this noise you must insulate the wheel-arches, the door panels and the bottom. Preferably, for the bottom and the wheel-arches you should use Vibraflex Extreme for this purpose. Use Vibraflex Normal for the doors. Use (V) for the floor pan and extend it as far as possible behind the pedals, having previously made sure that it can be covered with a car carpet.

Step 3: Insulation

The remaining driving noise that you hear comes through the chassis and it can be further reduced by insulation (adding mass). You insulate by covering the floor pan (as far as possible behind the pedals with the Isomat VM floor mat: this floor mat has a high mass, an anti-slip upper layer and a pleasant appearance, so it can be used as floor covering.
