Driving a car is always accompanied with the noise of a working engine and other different side noises such as (street noises, road sound from the wheels, plastic interior squeaking etc.).
These consequences make negative influence on the comfort of driver and passengers. They are one of the reasons of fast tiredness and as a result, loss of concentration, which is vital, when travelling on long distances. Most of modern vehicles have pretty bad factory sound insulation, due to economy on materials thickness (metal, plastic).
The solution to this problem has been found long time ago. It is a partly- or full vehicle soundproofing, which includes in it sound- and especially vibration damping of the most troubled car parts, such as: doors, wheel arches, floor, hood and roof. Soundproofing gives you a stunning effect, as if you had a premium class car.
