The ranking of the most quiet and the most noisy car
As is known,the noise in the car can have a big impact on the driver, causing fatigue and nervousness. The sound of the engine, suspension, tires and rolling wind – this is only part of the sources of acoustic discomfort. Automakers are struggling with them, improving noise and aerodynamics. Success is on their side: modern cars are much quieter for those who are sitting in the cabin. At least some of them.

In the conditions of our roads the role of soundproofing the car increases.This challenge can be overcome by installing additional sound absorbing materials in the engine compartment, wheel arches, doors and trunk, and lower vibrations of the body due to the more stringent damping.
