1. Acoustic board: Acoustic board is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquet, simple construction, good stability, good impact resistance, good independence, and high cost performance. It is rich A variety of colors are available to meet the needs of different styles and levels of sound-absorbing decoration.
Wood wool sound-absorbing panels are very popular in indoor sound insulation materials, and this panel is mainly made of poplar wood fiber. The wood wool sound-absorbing board is simple to install, and it is more elegant than sound-absorbing cotton, and the sound insulation effect is also good. If you are a music enthusiast, or want to use a recording studio at home, then you can choose this material.
2. Sound-absorbing cotton: It is a kind of man-made inorganic fiber. The main raw materials are quartz sand, limestone, dolomite and other natural ores, and some chemical raw materials such as soda ash and borax are used to melt into glass. In the melted state, it is blown by external force into flocculent thin fibers. The fibers and fibers are three-dimensionally intersected and entangled with each other, showing many small gaps. Sound-absorbing cotton is the most common sound insulation material indoors. The construction is convenient, it is also moisture-proof and waterproof, and has good air permeability. However, the flame retardancy of sound-absorbing cotton is not good, and other flame-retardant measures need to be taken for indoor use. Glass wool, rock wool, polyester fiber sound-absorbing cotton, glass wool and rock wool are easy to cause respiratory tract allergies, so it is not recommended to use it. Polyester fiber sound-absorbing cotton has better sound absorption effect for middle and high frequency, but poor absorption for low frequency sound. The gradient sound-absorbing cotton in the polyester fiber sound-absorbing cotton is good, and the absorption effect of low frequency, intermediate frequency and high frequency sound is very good, and the sound absorption efficiency is high.
3. Sound insulation board: Sound insulation board is a section that acts on the sound insulation effect. There are sound insulation classifications for buildings and structures. The sound insulation board does not block all frequencies of sound. Objects have a natural resonance frequency. Sounds close to the object's resonance frequency will significantly reduce the sound insulation effect of the sound insulation board.
The sound insulation board has the difference between air sound insulation and vibration sound. Airborne sound insulation board, that is, the board that blocks the sound transmitted in the air. Vibration and sound insulation panels are panels and systems that block the sound transmitted in rigid components (such as reinforced concrete monolithic houses). The board made of soft fiber or PMMA material or polycarbonate board is commonly called sound insulation board. The sound insulation effect of the sound insulation board is different. After processing, the sound insulation effect is good, we call it the sound insulation board. When choosing a sound insulation board, we must check the relevant test report, so as not to buy the sound insulation board is not soundproof.
