Nowadays, sound-absorbing boards are used in many places, such as TV stations, concert halls, conference centers, gymnasiums, shopping malls, hotels, cinemas, libraries, hospitals and other places. They are ubiquitous and bring many conveniences to our life.

As far as home decoration is concerned, most of them use wooden sound absorbers. It is based on the principle of acoustics refined processing, by decorative core material and sound-absorbing thin felt composition. Wood sound-absorbing board is divided into slotted wood sound-absorbing board and orifice wood sound-absorbing board. Generally speaking, the wooden sound-absorbing board used in the house mainly consists of orifice wood sound-absorbing board, which penetrates into the material through a large number of tiny connected holes in the material, and converts the sound energy into heat energy by friction with the material, so as to achieve the resonance sound-absorbing of the thin plate, which is also intense through the thin plate. Vibration absorbs a lot of sound energy, and with the increase of frequency, the sound absorption coefficient gradually increases, that is, high frequency absorption is better than low frequency absorption, and finally meets the requirements of sound absorption. In addition, it can also improve the quality of sound and improve the clarity of speech. According to the understanding of the building materials market, different consumers'needs, sound-absorbing boards have solid wood veneer, paint surface, imported baking paint surface and other various decorations, can be selected according to different styles of the home, but also according to the actual situation of the owners, decorating sound-absorbing boards in specific locations, so as to achieve both beauty and reality. Use the effect, play the role of family noise reduction.

There is also a commonly used sound-absorbing material, metal perforated sound-absorbing plate, with round holes, square holes, long round holes, rectangular holes, triangular holes, size combination holes, etc., the bottom plate is mostly white or aluminium. Because the insulation performance of metal sheet is poor, in order to obtain certain sound absorption and heat absorption function, when choosing metal sheet for ceiling decoration, we can use the method of adding glass wool, rock wool and other insulation and sound absorption materials to achieve the effect of insulation and sound absorption.

In addition, there are fabric sound absorption board, mineral wool sound absorption board, aluminum honeycomb perforated sound absorption board, polyester fiber sound absorption board and other types of sound absorption board. Different sound absorption boards are used in different places, and the requirements for sound absorption effect are naturally different.

Sound-absorbing board is a kind of material with sound-absorbing and noise-reducing function. Wood sound-absorbing board is elaborately processed according to the principle of acoustics. It consists of veneer, core material and sound-absorbing felt.

Wood sound-absorbing board is divided into grooved wood sound-absorbing board and orifice wood sound-absorbing board. The grooved wood sound-absorbing board is a narrow resonant sound-absorbing material with grooves on the front and perforations on the back of the density board. The orifice wood sound-absorbing board is a structural sound-absorbing material with circular holes on the front and back of the density board. Two kinds of sound absorption boards are often used for wall and ceiling decoration.
