Acoustical treatment materials can be roughly divided into sound absorption materials, diffusion materials and sound insulation materials according to their functions.

Acoustical treatment materials can be roughly divided into sound absorption materials, diffusion materials and sound insulation materials according to their functions. Among them, the sound-absorbing material is not only the conventional sound-absorbing plate, but also the low-frequency trap which is usually used to absorb low frequencies. First of all, we need to know how the sound will continue to spread after it has spread to our common walls.

Incident sound-reflected sound = sound absorption coefficient

Incident sound-transmitted sound = transmission loss

Some of the sound is absorbed by the wall and turned into heat energy.

From the above relationship, it is not difficult to find that sound insulation can only ensure as little transmitted sound as possible, but it does not necessarily have a good sound absorption effect.

sound absorbing material
Traditional sound-absorbing materials are porous materials, or the scientific name is acoustic resistance sound-absorbing materials. The essence of sound wave is a kind of vibration, exactly speaking, it is air vibration for the speaker system. When air vibration is transmitted to this sound-absorbing material, it will be gradually relieved by the fine pore structure and converted into heat energy.

Generally speaking, the thicker the sound-absorbing material is, the more such small holes are in the direction of sound propagation, and the better the absorption effect of sound incident immediately or at a small angle is.

Diffusion material

When the sound is incident on the wall, some sound will exit along the geometric direction and continue to spread, but usually this process is not an absolute "specular reflection". If it is an ideal absolute reflection, the sound should exit completely in the geometric direction after passing through the surface, and the energy in the exit direction is consistent with the incident direction. The whole process does not lose energy, which can be understood as no diffusion at all, or more popularly as specular reflection in optics.

sound insulating material
The sound insulation and sound absorption properties of materials are different. Sound-absorbing materials often use the pore structure in the material. However, this pinhole structure usually leads to the transmission and propagation of sound waves. However, in order to prevent the sound from further transmitting from the material, it is necessary to reduce the cavity structure as much as possible and increase the density of the material.

Usually, the sound insulation performance of sound insulation materials is related to the density of materials. Buying high-density sound insulation materials can further improve the sound insulation performance of the room. However, the single-layer sound insulation material sometimes still has limitations. At this time, double-layer sound insulation treatment can be adopted, and additional damping materials can be added to the two-layer sound insulation material. However, it should be noted that the two layers of sound insulation materials should be avoided as much as possible to adopt the same thickness, so as to avoid repetition of coincidence frequency. If in the actual construction and decoration, the whole house should be soundproofed first, and then sound absorption and diffusion treatment should be carried out.

Sound absorption treatment in audio-visual appreciation room

The front wall is decorated with perforated sound-absorbing board of ecological wood Great Wall as a rigid diffusion sound-absorbing structure for film appreciation. Irregular wood veneer is pasted on the pillars on both sides to reflect sound.

According to the acoustic sinking structure of the original beam ceiling, the top surface is decorated with fake beams, and the customized sound-absorbing wedge is hoisted inside the sinking to play the role of sound absorption and diffusion.

According to the final requirements of acoustic calculation, the side elevation is made of composite sound-absorbing structure and diffusion structure, all supporting pieces such as additional keels are irregularly designed for earthquake resistance, and the external decoration is made of polyester fiber sound-absorbing board.

Introduction of commonly used sound-absorbing materials

Polyester fiber sound-absorbing board

Polyester fiber sound-absorbing board is called polyester fiber decorative sound-absorbing board, which is a decorative material with sound-absorbing function made of polyester fiber by hot pressing.

100% polyester fiber is hot-pressed by high technology and made in the shape of cocoon and cotton, which realizes density diversity and ensures ventilation, and becomes an excellent product in sound-absorbing and heat-insulating materials. The highest sound-absorbing coefficient reaches above 0.9 in the noise range of 125 ~ 4,000 Hz. According to different needs, the reverberation time is shortened, the sound impurities are removed, the sound effect is improved, and the language clarity is improved. The product has the characteristics of decoration, thermal insulation, flame retardant, environmental protection, light weight, easy processing, stability, impact resistance and simple maintenance. Become the preferred decorative sound-absorbing material for interior decoration.

Sound-absorbing property The sound-absorbing property of polyester fiber sound-absorbing board is similar to that of other porous materials. The sound-absorbing coefficient increases with the increase of frequency, and the sound-absorbing coefficient of high frequency is very large. The sound-absorbing property of the material can be greatly improved by leaving a cavity on its back and the space sound-absorbing body made of it. The noise reduction coefficient is about 0.8 ~ 1.10, making it an efficient sound absorber with wide frequency band.

Wood wool sound-absorbing board

Wood wool sound-absorbing board’s surface texture shows elegant texture and unique taste, which can fully interpret the designer’s creativity and ideas. This product combines the advantages of wood and cement: it is as light as wood, as firm as cement, and has many functions such as sound absorption, impact resistance, fire prevention, moisture prevention and mildew prevention, and can be widely used in stadiums, theaters, cinemas, conference rooms, churches, factories, schools, libraries, swimming pools and so on.

Wood wool sound-absorbing board is made of poplar fiber, combined with unique inorganic hard cement adhesive, by continuous operation technology and under high temperature and high pressure. This product has physical characteristics that can only be obtained by synthesizing several different building materials.

Unique appearance, good sound absorption-unique surface filiform texture, giving people a primitive and rough feeling, satisfying the concept of modern people returning to nature. The surface can be painted and painted, and it can be painted for six times. The maximum sound absorption rate can reach 1.00.

Wood sound-absorbing board

Wood sound-absorbing board can be divided into two types: grooved wood sound-absorbing board and perforated wood sound-absorbing board. Grooved wood sound-absorbing board is a kind of slit resonance sound-absorbing material with slots in the front and holes in the back of MDF. The perforated wood sound-absorbing board is a kind of structural sound-absorbing material with round holes on the front and back of the MDF. Two kinds of sound-absorbing boards are often used for wall and ceiling decoration.

Cross-sectional structure of wood sound-absorbing board: the principle of sound-absorbing board: There are many small holes on the surface of sound-absorbing board. After the sound enters the small holes, it will be reflected randomly in the inner wall of the structure which is a bit like a sponge until most of the energy of sound waves is consumed and turned into heat energy, thus achieving the effect of sound insulation. There are many tiny gaps in the sound-absorbing board, which have a sound-absorbing effect on sound waves, especially for sound waves with frequencies higher than 600Hz.Introduction of commonly used sound-absorbing materials.
