Living in a noisy big city, we definitely need to choose a good soundproofing material, so as to reduce the noise in the room and ensure the quality of our sleep. So, today I will share with you what are the soundproofing materials and how to choose soundproofing materials, you can learn about it!
1. What are the sound insulation materials?
1. Sound-absorbing cotton.
What are the soundproofing materials? Generally, it is more common in our room is sound-absorbing cotton, which is easy to process, moisture-proof and waterproof, and has better breathability compared with other materials. The only deficiency of sound-absorbing cotton is that the flame retardancy is not good, and it cannot be well isolated from the spread of fire, so those who have sound-absorbing cotton installed in the shed at home should pay attention to fire prevention.
1. Wood wool sound-absorbing panel.
What are the soundproofing materials? Like wood wool acoustic panels, it is a more popular soundproofing material. Wood wool sound-absorbing panels are generally made of poplar fiber, with a clear and natural texture, which satisfies everyone's pursuit of nature.
The wood wool sound-absorbing board is high-end and atmospheric, and the sound insulation effect is very good, and it is generally used in KTV, opera houses and other places.
3. a soundproof panel.
What are the soundproofing materials? Each material has a sound insulation effect, after special processing, its density becomes higher, and the sound insulation effect is also better, we call it a sound insulation board. If not, it means that the sound insulation effect of the sound insulation board is poor, and it is recommended not to choose.
Second, how to choose sound insulation materials.
1. Density. Density is directly proportional to the volume of sound insulation, and the higher the density of the soundproofing material, the better its sound insulation. Therefore, the higher the density and mass of the same sound insulation material per unit area, the better the sound insulation.
2. Flexibility. If the elasticity is good, it can reduce the vibration of the hard board due to sound waves and increase the effect of sound insulation. The method of testing the elasticity of the soundproof felt is to cut the soundproof felt into two or three centimeters wide strips, and stretch it with both hands.
3. Toughness. A good sound insulation material is not only elastic, but also very tough. When we check the sound insulation material, the sound insulation material is folded in half and pressed hard, a good sound insulation material will not break, and the original is the same after being loosened, and the surface is as smooth as new.
Inferior sound insulation materials can easily break, or the surface may be warped or deformed.
4. Pull. Tear the soundproofing material by hand to see if it is easy to tear it. A good soundproofing material is difficult to tear if you don't use tools such as knives and scissors. If it is an inferior soundproof material, it will be torn by hand, so you must choose carefully.

1. Soundproof cotton is a kind of artificial inorganic fiber, which has a compact structure, high sound absorption, not easy to deform, and is very cost-effective.
2. Sound insulation felt is a medium-grade sound insulation material. When in use, it is generally used with gypsum board, mainly used for sound insulation of walls and ceiling areas. The material is soft and thin, environmentally friendly and easy to construct.
3. Sound insulation board is a common wall sound insulation material, and the sound insulation effect of sound insulation board is very good, and it can be used for sound insulation in different places.
4. The wall damping pad is made by a unique process, which is made of olefin damping pad material foam, and adopts a unique flexible closed-cell structure, which can well control and buffer the propagation of sound, and is an ideal wall sound insulation material.

1. Soundproof sponge. Sponges have good sound absorption properties, and sponges will be used in the recording studio to achieve sound insulation. In particular, the wavy cotton surface is treated with sound-absorbing grooves, which has a better sound-absorbing effect and can be used as a soundproof material for windows.
However, due to the strong water absorption capacity of the sponge and the easy absorption of water on rainy days, it may cause the iron frame on the window to rust, and it is still very practical if the window does not rain.
2. Acoustic felt. The raw materials of soundproof felt are made of elastic materials such as rubber and plastic, and have a certain flexibility of high-density membrane, which can be matched with gypsum board for wall insulation and ceiling sound insulation, and can also be placed in pipes and other areas for sound insulation and damping and vibration reduction. The application range of soundproof felt is very wide, you can use soundproof felt and gypsum board to make soundproof walls, ceiling soundproofing can also be made of soundproof felt, or sewer pipes to tell the hungry road, etc.
3. Polyurethane foam. Polyurethane foam is the main component of styrofoam. The polyurethane foam material has good sound insulation and sound absorption properties, and has anti-corrosion, waterproof and flame retardant design, which is a good choice for sound insulation materials.
4. Insulating glass. The insulating glass is composed of two or more layers of glass, and two or more pieces of glass are bonded to the aluminum alloy frame by using a composite sock adhesive with high strength and air tightness, leaving space between the sealing glass, and adding inert gas to obtain excellent thermal and sound insulation performance. Because of the poor heat transfer properties of the air or gas encapsulated in the glass room, it can produce a good sound insulation effect.

1. Foam fiber is a good soundproof material, and it is cheap. If it is in the living room, it is recommended that the wall be made of "soft packaging", which has good sound insulation and is beautiful.
2. Commonly used sound insulation materials include: steel, glass, reinforced concrete, aerated concrete, solid brick, granite, marble, oak, plywood, gypsum board, cement pressure board, calcium silicate board.
There are many of the following:

First of all, you have to understand why you are banned.
Usually there are 3 reasons for the ban, one is the high-frequency banning, which causes harassment by dialing ** at multiple frequencies at the same time, and the account is blocked when it is detected, and the other is the complaint and the account is blocked, and there is a quarrel with the customer. There are even abusive words, customers have evidence to complain about recordings, and the third is to use cards to seal the number in different places, and play ** across provinces and multiple frequencies, which was detected by the Anti-Fraud Center of the Ministry of Public Security, the same number of bans, of which high-frequency banning is the biggest reason. >>>More
