For the doors

The vehicle doors are isolated to reduce external noise and microvibrations of metal surfaces as well as improving heat insulation and enhancing the overall vehicle acoustics. The following systems are incorporated in each door:

Layer One	Vibration cushioning material "Alumast"
Layer Two	Heat insulating material SGM-izol
Layer Three	Vibration cushioning material "Alumast"
Layer Four	Sound absorption material "Violon Beta"
Layer Five	On the vibration cushioning material, a layer of sound absorption material: Violon VEL Wave
Layer Six	On the plastic of the cover, a layer of vibration cushioning material: "Alumast"

The effect of this processing:

An increase in soundproofing against external noises not less than 2-4 dB for separate frequencies, increasing the soundproof characteristics of the door to 3-5 dB for separate frequencies.
