Sound absorption materials: a bit of theory

Noise absorbing materials are characterized by a special structure and working principle. And their effectiveness depends on the thickness of the polyurethane foam from which they are made - the thicker, the more better. For example, Samoff Hermeton A7 has a thickness of the polyurethane layer is 7 mm, A15 - 15 mm, A30 - 30 mm. on Top of this insulation, as vibrocentercovered with a special protective film.

We would like to mention another domestic producers , Shumoff Comfort, which also belongs to this category of materials for acoustic insulation, but is made of foam-rubber is comfortable to cutting leaves. The benefits of this silencer weight:

• he is able to serve up to 20 years without changing its operational characteristics;
• very flexible, flame retardant and can perform their functions in a large temperature range, so it is often used in okolomatocnah space;
• flame retardant;
• not only absorbs noise, but also improves the thermal insulation car;
• not destroyed under the influence of moisture, microorganisms, and ultraviolet radiation;
• it is possible to repeatedly compress and decompress without compromising the integrity of layers, allowing you to use it to seal the joint of plastic interior parts.

Sound-absorbing materials can be used for complex processing of car, and as the acoustic tuning of the car. Can be pasted on the inner panel of the door or on the hood. If you do not perform such processing, even the quality speakers will sound not as it should be. Also they can be finished with a Luggage compartment (assuming you install it Saba) and ceiling panels.
