Any noise isolation can be divided into several types which use the following: noise vibration and skripoizoliruyuschie. Vibration isolation - can reduce the noise caused by vibration of the various units of automobiles. Vibration isolation is also necessary to install high-quality speaker system to remove unnecessary sounds and resonances of the elements that prevent the car listening to music. To do this, it is best to use the Vibration Reducing self-adhesive sheet material consisting of mastic adhesive layer on the rubber base and aluminum foil. - is the removal of the sounds associated with the "festivities" car body and its individual elements in the motion. As a result, "sound" plastic parts car - dash trim car doors, etc. To remove these sounds requires painstaking work on sizing the joints of plastic parts with a special material resembling foam on the adhesive base. Commonly used porous sound-absorbing special materials.
Noise isolation - a distinctive feature of these materials is that they do not absorb moisture and have a "closed pore" what and provides isolation. Such materials are usually processed wheel arches compartment floor to wall to the engine compartment. Under the hood where temperature is usually quite high, using special non-combustible materials with a special heat-reflecting layer. For a layer of sound insulation is applied Isolon teip Isolon teip 3004 and 3008. Isolon grade pes - physically crosslinked penopoelitilen. Due to radiation crosslinking molecular structure of the material labeled pes gets cross-connected or mesh model which significantly increases the durability and resistance of the material mechanical and temperature influences. Density range: 25 - 200kgm3. Operating temperature range: -60 +100. Thus the total processing "noisy" original car (installing soundproofing) includes all three components: the noise-vibration-and and also may need and the local vibration isolation when installing music in a very quiet class car.
