Most of these noises occurs in the audible human ear range from 20 to 20,000 Hz. Every single sound can be very loud and intense, but put together, they create a cacophony that not only can ruin the sound of your favorite music, but also seriously affect the mental and physical health.

Vibrocenter is a sheet material that suppresses the low-frequency component of the noise that lies within the range of 20 to 500 Hz. due to the damping of its amplitude. It is glued on the body parts of the car (floor, ceiling, doors, wheel arches). They are made mainly of bitumen, silicone, or rubber. From the outside the vibration damper often covered with foil which increases its sound insulating properties.

Shumoglushiteli looks very similar to conventional fine-meshed foam, but its sound-absorbing properties are much more. The structure of this material is that it consists of a maze of small empty cells, which absorb the sound waves. The effectiveness of sound-absorbing materials depends on their thickness. They are made primarily from polyurethane foam.

By combining these two types of noise reduction, you can get the car high quality sound. You can do it alone in my garage, and with the aid of professionals.
