The Art of Soundproofing

the art of soundproofing

To enjoy significant sound-proofing results, one needs to understand the different kinds of noise in a car.
There are mainly:-
1) Structure borne vibration
2) Air-borne noise
3) Wind tunnel noise from the hollow sections.

To address these, we source the globe for the Best products. Some are the very same solution that luxury marques like Lexus, Mercedes uses.

Knowing WHERE , WHAT and HOW MUCH is the key as much as the material itself. This is KL AUTO’s expertise.
