How to make indoor soundproof walls?
1. Positioning of the elastic line of the sound insulation wall: According to the construction drawing, release the position control line of the movable partition wall on the indoor floor, and lead the position line of the partition wall to the side wall and the top plate. The elastic line is the installation position line of the fixed parts that should be ejected.
2. Installation of sound-proof wall track fixtures: select track fixtures according to the design requirements. Before installing the track, consider the closing method of the wall, ground, and ceiling and facilitate the installation of the movable partition wall, and calculate the weight of the movable partition wall. Determine the load to be borne by the track and the specifications and fixing methods of the embedded parts. The embedded parts of the track should be installed firmly, the track and the main structure should be fixed firmly, and all metal parts should be treated with rust prevention.
3. Prefabricated partitions for soundproof walls: First, determine the net size of the movable partition according to the design drawings and the actual size measured on site, and then calculate and determine the movable partition according to the installation method of the track, the net size of the movable partition and the design division requirements The size of each partition is finally drawn out and commissioned for processing. Since the movable partition wall is a movable wall, it is required that each partition should be as beautiful and delicate as a decorative door. It should be prefabricated by a professional manufacturer, and the quality of the product can be ensured through processing and trial assembly.
What kind of soundproof wall is good?
1. Sponge. Sponge is a kind of sound-absorbing material with very good performance. Usually, a large number of sponges are used in the recording studio to achieve the sound insulation effect. The sound-absorbing effect of sponges with sound-absorbing grooves on the surface is better.
2. Polyurethane foam. Polyurethane foam is the main component of styrofoam. The cured polyurethane foam has good sound insulation and sound absorption performance, and is anticorrosive and waterproof. The better polyurethane material has a flame-retardant design and is a good choice for sound insulation materials. .
3. Calm sound-proof and sound-absorbing cotton. Calm sound-proof and sound-absorbing cotton uses industrial rubber and plastics as the carrier, added with various specifications of sound-proof particles, formed by nitrogen foaming, and has a gray-black appearance. Its front is covered by miniature sound-absorbing holes and special-shaped sound-absorbing grooves, which efficiently filter noises of different frequencies and wavelengths, integrate sound insulation and sound absorption functions, and meet the requirements of light-weight and environmentally friendly home decoration sound-proof materials, and it is cost-effective.
4. Sound insulation damping felt. The sound insulation damping felt is refined by introducing advanced foreign technology from a variety of organic minerals in a certain proportion. The sound insulation felt has good wide-band sound insulation performance and high damping performance. It is a new type of sound insulation material that controls the attenuation of noise in the transmission path.
5. Sound insulation blanket. Professional sound insulation material. This material has excellent broadband sound insulation properties and high damping properties, which can effectively isolate all kinds of airborne sound. The sound insulation effect of sound insulation walls combined with gypsum board and sound-absorbing cotton is very good. In the wall decoration, it is best to make the wall uneven. For example, use wallpaper, wall covering and other materials to do some decoration. They have very good noise reduction effects.
