1, sponge.
Sponge is a kind of sound-absorbing material with very good performance. Usually, a large number of sponges are used in recording studios to achieve sound insulation. Sponges with sound-absorbing grooves on the surface have better sound-absorbing effect. This kind of sponge is usually called wave cotton. It's just that sponges have strong water absorption ability and are easy to absorb dust. If it is used as a sound insulation material for windows, it will easily absorb water in rainy days or when it is wiped with a wet cloth, so that the iron frame on the windows will rust. But now many people's windows are not drenched by rain, so they are still very practical. You can also reconsider when you choose.
2. Polyurethane foam.
Polyurethane foam is the main component of foamed rubber. The cured polyurethane foam can play a good role in sound insulation and absorption, and it is also anticorrosive and waterproof. Moreover, the better polyurethane material has flame retardant design, which is a good choice for sound insulation materials.
3, stable sound insulation and sound absorption cotton.
Steady sound-proof and sound-absorbing cotton takes industrial rubber and plastic as the carrier, adds various specifications of sound-proof particles, and is formed by nitrogen foaming, and its appearance is gray-black. Its front is covered with miniature sound-absorbing holes and special-shaped sound-absorbing grooves, which effectively filters noises with different frequencies and wavelengths, integrates the functions of sound insulation and attraction, meets the requirements of light weight and environmental protection of home improvement sound insulation materials, and has high cost performance.
4. Sound insulation and damping felt.
Sound insulation and damping felt is made of a variety of organic minerals by introducing foreign advanced technology in a certain proportion. The sound insulation felt has good broadband sound insulation and high damping performance. Controlling the attenuation of noise on the propagation path is a new type of sound insulation material. The mixture of high-density special materials has achieved very good sound insulation and noise reduction effect, which makes the sound insulation felt show excellent performance in isolating air sound and impact sound. The sound energy is greatly lost in the sound insulation material, and the isolation effect on medium and low frequency noise is incomparable to other materials. It is an excellent multi-purpose sound insulation material.
5. Sound insulation blanket.
Professional sound insulation material, with excellent broadband sound insulation characteristics and high damping, can effectively isolate all kinds of air-borne sound. The sound insulation wall made of it, gypsum board and sound-absorbing cotton has a very good sound insulation effect. In the wall decoration, it is best to make the wall a little concave and convex, such as using wallpaper, wall covering and other materials to do some decoration, and their noise reduction effect is very good.
