Introduction to Sound Insulation Materials

Soundproof materials refer to a type of material, component, or structure that isolates, isolates, or separates noise propagating in the air. For sound insulation materials, in order to reduce the transmission of sound energy and block the propagation of sound, they cannot be porous, loose, or breathable like sound-absorbing materials. On the contrary, their materials should be heavy and dense, such as steel plates, lead plates, brick walls, and other materials. The material requirements for sound insulation materials are dense without pores or gaps; Has a significant weight. Due to the compactness of such sound insulation materials, it is difficult to absorb and transmit sound energy while reflecting strong energy, resulting in poor sound absorption performance.

The decibels in which the incident sound energy on one side of the material is related to the transmitted sound energy on the other side are the sound insulation of the material, usually represented by the symbol R (dB). Sound insulation materials or components may have different sound insulation effects due to different usage scenarios and testing methods. Sound insulation materials can attenuate the transmitted sound energy to 10-3-4 or less of the incident sound energy. For the convenience of expression, the sound insulation amount is expressed in decibels.

Through deep processing methods such as slitting, gluing, cutting, and molding. We manufacture various specifications and irregular specifications to meet the needs of industry manufacturers or other supporting enterprises such as hall decoration design, home appliance quality inspection, instrument testing, automotive molding, etc. We develop different specifications and models of sound insulation materials according to user needs. Sound insulation materials have structural characteristics such as density, weight, strong damping, high elasticity, water resistance, good weather resistance, oil resistance, and good flame retardancy.
