There are many materials with good sound insulation effect. Today I will choose some commonly used materials to let everyone know:

Rock wool: Rock wool is an insulating material made from basalt or other minerals. It has excellent sound insulation and sound absorption properties and can effectively absorb sound waves and reduce noise transmission.

Wooden materials: Wood itself has some soundproofing effect because it absorbs sound and reduces the transmission of noise. The use of wooden materials in architectural design can effectively insulate sound and create a quieter environment. Usually I see sound insulation panels and diffusion panels that improve sound effects.

Sound insulation felt: Sound insulation felt is a material with good flexibility and high density that can effectively isolate noise and vibration. Cheap and widely used, it is suitable for indoor wall, ceiling and floor sound insulation.

Fiberboard: Fiberboard is a board made of fiber as the main raw material. It has high density and good sound insulation properties. It is often used for sound insulation on walls, ceilings and floors. Ordinary fiberboard is cheap, easy to make, and widely used.

There are many commonly used sound insulation materials on the market. As people pay more and more attention to noise pollution, more sound insulation materials have been developed. The quality of sound insulation is related to factors such as the density, thickness and installation method of the material. When choosing sound insulation materials, you should choose suitable materials based on actual needs and budget. In addition, the sound insulation effect of different materials may be different at different frequencies, so in actual applications, it may be necessary to select the most appropriate sound insulation material based on the noise source and frequency characteristics.
