Beijing China Railway First Group Metro Line 4-High-Strength Shock-Absorbing Sound Insulation Mat

Project Case

Beijing China Railway First Group Metro Line 4

High-strength shock-absorbing sound insulation mats are a type of sound insulation and shock-absorbing pad that have been specially treated to form a concave-convex pyramid shape on one side. The interior is filled with tiny voids and semi-open structures, which can absorb a large amount of the energy of the incident sound waves to form sound standing waves, thereby attenuating the sound waves. They can reduce the interference and reverberation of indoor reflected sounds and improve the purity of the sound. They are high-performance products of sound-absorbing and shock-absorbing materials.
