What material is used for movable partition? Sound insulation effect is good and safe?
1. Sponges.
Sponge is a kind of sound-absorbing material with good performance. Usually, a large number of sponges are used in recording studio to achieve sound insulation effect. The sponge with sound absorption groove on the surface has better sound absorption effect. This kind of sponge is often called wave cotton. It's just that the sponge has strong water absorption capacity and is easy to absorb dust. If it is used as a sound insulation material for windows, it will absorb water easily on rainy days or when you wipe it with a wet cloth, so it will rust the iron frame on the window. However, many people's windows can't be drenched with rain now, so it's still very practical. You can think about it when you choose.
2. Polyurethane foam.
Polyurethane foam is the main component of foam adhesive. The cured polyurethane foam material has good sound insulation, sound absorption performance, corrosion resistance and water resistance, and good polyurethane material has flame retardant design, which is a good choice for sound insulation material.
3. Quiet sound insulation and sound absorption cotton.
Quiet sound insulation and sound-absorbing cotton with industrial rubber and plastic as carrier, adding various specifications of sound insulation particles, nitrogen foam molding, gray black appearance. Its front is covered by micro sound-absorbing holes and special-shaped sound-absorbing slot, which can effectively filter the noise of different frequencies and wavelengths, and integrates the functions of sound insulation and absorption, so as to meet the requirements of lightweight and environmental protection of household sound insulation materials, with high cost performance.
4. Sound insulation and damping felt.
The sound insulation and damping felt is a new type of sound insulation material with good sound insulation performance in wide frequency band and high damping performance. It is a new type of sound insulation material to control the attenuation of noise in the transmission path. The high-density special materials have achieved very good sound insulation and noise reduction effect after mixing, which makes the sound insulation felt show excellent performance in isolating air sound and impact sound. The sound energy loss in the sound insulation material is large, and the isolation effect of medium and low frequency noise is incomparable with other materials. It is an excellent multi-purpose sound insulation material.
5. Sound insulation blanket.
Professional sound insulation materials, this material has very excellent broadband sound insulation characteristics and high damping, can effectively isolate all kinds of air transmission, with it, gypsum board, sound absorption cotton combination of sound insulation wall sound insulation effect is very good. In the wall decoration, it's better to let the wall have some concave and convex, such as using wallpaper, wall cloth and other materials to do some decoration, their noise reduction effect is very good.
