We all found that the life of the noise pollution has become very serious, let's say the city of the noisy sound of the car horn is very headache. In order to avoid the impact of noise on society, people are now in the roads, buildings, bridges and other infrastructure construction are using some sound-absorbing materials! This is something that everyone should feel! Sound-absorbing materials are very many types, I think we do not have much understanding in these areas! Next, I will introduce you to some of the sound-absorbing materials, some of the things it!
What are the sound-absorbing materials?
1, porous acoustic materials: mineral wool, glass wool, felt, wood wool acoustic panels and other porous materials, have a good absorption of high-frequency, leaving behind the air layer, but also to absorb the low-frequency.
2, perforated panels *** vibration absorption structure: perforated plywood, perforated fiber cement board, perforated paper gypsum board, perforated metal panels and other general absorption of mid-frequency, combined with porous materials to absorb the medium and high frequencies, behind the large cavity can also absorb low frequencies.
3, film acoustic structure: plastic film, canvas, artificial leather and other film is a medium-frequency sound-absorbing materials, film and its back to the cavity composed of film acoustic structure can be absorbed by the low and medium frequencies.
4, space acoustic body: the acoustic material into a variety of shapes of space acoustic body hanging in the air, because of its acoustic area than the projected area is much larger than the projected area of the projected area of the acoustic coefficient can be greater than 1. Bar acoustic body hanging in the acoustic energy flow in the location of the location of the density of the sound flow (for example, close to the source of the place, reflections have a focus on the place) with a better acoustic effect. The result is that the sound is absorbed by the sound absorber.
5, curtain: with breathable textiles as a curtain, away from the wall or window a certain distance from the installation, as a porous material behind the set of air layer, on the middle and high frequencies have a certain effect of sound absorption.
What are the indoor sound-absorbing materials
1. Fabric sound-absorbing board
Indoor sound-absorbing materials fabric art sound-absorbing board, fabric sound-absorbing board is globally recognized as having a strong sound-absorbing effect of the centrifugal glass wool, but also this material is widely used in the acoustic materials Industry production, has a strong sound absorption, sound insulation effect, more durable, lighter quality, mildew and moisture, and a variety of colors, decorative effect is very good-looking.
2. Metal sound-absorbing board
If you choose metal sound-absorbing board as indoor sound-absorbing material, it is also excellent. Metal sound-absorbing board with many small holes, which is called metal perforated sound-absorbing board, this sound-absorbing board has a muffling, sound insulation, and beautiful and durable, more environmentally friendly, easier to install.
3. Mineral wool sound-absorbing board
If you think the mineral wool sound-absorbing board is good, with mineral wool sound-absorbing board to use as indoor attraction material, has a strong decorative effect, I saw the first eye mineral wool sound-absorbing board, far from seeing some tiny dots, but close look, only to find that are some shades of holes, the surface form is more special!
4. Wooden acoustic panels
Wooden acoustic panels, is also one of the indoor acoustic materials. Wooden sound-absorbing board is made of wood materials, in its surface layer added a layer of sound-absorbing materials, the surface of the reduction of the wood principle, the realization of the simple and natural, reflecting the modern rhythm of the bright and beautiful style, with the aroma of wood, wooden sound-absorbing board decorative strong, but also in line with national standards and manufacturing.

Through the editor's detailed introduction to the types of sound-absorbing materials you should now have a certain understanding and awareness of it! With the continuous development of society, now sound-absorbing materials in the society of the major industries in great demand, almost all walks of life will be involved in some soundproofing materials! So we do some understanding is also very necessary, the impact of noise on us is very large, so in our daily lives we should try to avoid making noise! This will seriously affect our lives.
