Wooden sound-absorbing board is finely processed according to the acoustic principle, and is composed of veneer, core material and sound-absorbing felt.Wooden sound-absorbing board is divided into grooved wood sound-absorbing board and perforated wood sound-absorbing board.
② Mineral wool sound-absorbing board: mineral wool sound-absorbing board has rich surface treatment forms and strong decorative effect.Knurled type with surface treatmentMineral wool board, commonly known as "caterpillar", the surface is covered with holes of different depth, shape and aperture.
③Fabric sound-absorbing board: Fabric sound-absorbing board - the core material isCentrifugal glass wool。Centrifugal glass wool, as an acoustic material widely used in the world for a long time, has been proved to have excellent sound absorption performance.

Theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, gymnasiums, lecture halls, multi-function halls, hotel lobbies, hospitals, shopping malls, schools, piano rooms, conference rooms, studios, recording rooms, KTV rooms, bars, industrial plants, machine rooms, home noise reduction and other places with high requirements for acoustic environment and high-grade decoration.
fourpolyesterSound absorption board is an ideal sound absorptionDecorative materials。Its raw material is 100% polyester fiber, which has the advantages of sound absorption, environmental protection, flame retardancy, heat insulation, heat preservation, moisture-proof, mildew resistance, easy dust removal, easy cutting, parquet, simple construction, good stability, impact resistance, good independence, high cost performance, etc. There are a variety of colors to choose from, which can meet the demand for attraction and decoration in different styles and levels.
fiveSound absorbing wedgeIt is a special sound absorption structural material used for strong sound absorption field. It is formed and cut with porous (or fibrous) materials to form a cone or wedge shaped sound absorber, which is firm and does not deform.The sound absorption wedge is suitable for strong airflow environment. Its main object is high-quality anechoic chamber. It can absorb low frequencies more effectively, eliminate standing waves, and meet the requirements of eliminating echoes. The sound absorption coefficient of low cut-off frequency is greater than 0.99.Compared with ordinary sound absorption wedges, V-shaped and W-shaped sound absorption wedges made of polyester have the characteristics of small occupation volume and more reasonable price.
6 DiffuserSound-absorbing boardExcept with planeSound-absorbing boardIn addition to all the functions of, it can conduct sound waves from different angles through its three-dimensional surface, eliminate the blind area in the diffusion process of sound waves, improve the sound quality, balance the sound, thin the stress, weaken the treble, and compensate the bass.
