300, the train stops next to my house. What should I do if my room is loud every time I go there?

The easiest way is to do sound insulation when decorating.

First, the window: choose a soundproof window.

Whether our living room is ravaged by outdoor noise, especially in the road with more vehicles and the central station in the city, here is a little knowledge about soundproof windows for everyone to share.

The intensity of noise can be expressed in decibels (dB) of sound level. The noise level is 35 ~ 45 decibels, which is a quiet and normal environment; More than 50 decibels will affect sleep and rest; More than 70 decibels interfere with the conversation, causing upset and inattention; Working or living in a noise environment above 90 decibels for a long time will seriously affect hearing and lead to other diseases such as heart and blood vessels. At the same time, noise will also have psychological effects. Under high-frequency noise, most people are restless and easily excited. Living in a noisy environment for a long time is easy to make people feel irritable and depressed, which affects work efficiency. It is particularly worth reminding that the harm of noise will increase with the extension of contact time. Experts point out that if you are only exposed to strong noise for a short time, the sensitivity of hearing organs will decrease and will return to normal within a few minutes after leaving the noise environment. This situation is called auditory adaptation, which is a physiological protection phenomenon of human beings. However, if you are exposed to noise for a long time, your hearing will obviously decline, and it will take several hours or even dozens of hours to fully recover.

Second, the sound insulation board

When decorating the house, add a layer of sound insulation board to the interior wall, but it will take up some space.

Barriers (barriers)

Panels made of soft fibers, PMMA or polycarbonate are often called sound insulation panels.

The sound insulation board made of PMMA or polycarbonate has the characteristics of aging resistance, high temperature resistance, transparency, light weight and convenient installation.

Furniture material is an artificial board made of wood or other plant fiber materials through chopping, softening, pulping, forming and hot pressing. There are three kinds: hard, semi-hard and soft. Hard fibreboard is hard and dense, and can be used as the material of automobiles, ships, furniture, interior decoration of houses and packing boxes. Soft fiberboard is light and porous, which is a good material for heat insulation and sound absorption, so it is also called "sound insulation board".

The main characteristics of sound insulation board: on the premise of ensuring sound absorption and sound insulation effect, it has the characteristics of simple manufacture and installation.

1, large sound insulation: the average sound insulation is 37dB. (Conditional sound-absorbing cotton 48K, thickness 95 × height 500 × length 1000-3000)

2. High sound absorption coefficient: the average sound absorption coefficient is 0.84. (Conditional sound-absorbing cotton 48K, thickness 95 × height 500 × length 1000-3000)

3. Weathering resistance and durability: the product has water resistance, heat resistance and ultraviolet resistance, and its performance will not be reduced or its quality will be abnormal due to the change of rain temperature. The sound barrier of the product is made of resistance plate, galvanized resistance plate, glass wool and H steel column, and its corrosion resistance life is more than 15 years.

4. Sound insulation board is beautiful: you can choose a variety of colors and shapes to combine, and coordinate with the surrounding environment to form a beautiful landscape.

5. Economy of sound-absorbing board: Assembled construction can improve work efficiency, shorten construction time and save construction cost and labor cost.

6. Convenient sound insulation board: installed in parallel with other products, easy to maintain and update.

7. Safety of sound insulation board: Both ends of sound insulation board are connected and fixed with φ 6.2 steel wire rope to prevent secondary injury and personal and property losses.

8. Lightweight sound-absorbing board: Sound-absorbing board series products have the characteristics of light weight, with the mass of less than 20kg per square meter, which can reduce the bearing capacity of elevated light rail and elevated road and reduce the structural cost.

9. Fire prevention of sound insulation board: ultra-fine glass wool is used. Because of its high melting point and incombustibility, it completely meets the requirements of environmental protection and fire prevention laws and regulations, and the fire prevention reaches Grade A. ..

10, high strength: considering the different climatic conditions in different regions of China, wind load is fully considered in structural design. 1.0- 1 galvanized sheet. 6mm was used to press the groove with numerical control equipment to increase the strength, so that the product could resist 10- 12 typhoon and the compressive strength was 300kg/m2.

1 1. Waterproof and dustproof: The louver design fully considers waterproof and dustproof, and its angle is set at 450, so its sound absorption will not be affected in dusty or rainy environment. Dust removal and drainage measures are set in the structure to avoid water accumulation in the components.

12. The sound insulation board is durable: the product design fully considers the wind load of the road, the impact safety of traffic vehicles and all-weather open-air corrosion protection. The product is made of aluminum alloy resistance plate, galvanized resistance plate, glass wool and H-beam column. The company guarantees that the products will not be corroded or deformed within 15 years, and the sound absorption and sound insulation effect will not be reduced.

Uses of sound insulation board: urban rail transit sound insulation barrier, expressway sound insulation barrier, indoor sound insulation barrier, air conditioning and mechanical sound insulation barrier.

Third, soundproof doors.

At present, the commonly recommended sound-proof door design is generally filled with sound-absorbing cotton or PU, and some of them are just divided into so-called honeycomb structures with cardboard, which on the one hand increases the strength of the door panel, and on the other hand makes a certain degree of sound insulation with the closed air layer formed by it. Basically, any material has its sound insulation effect. Simply put, the heavier the mass, the better the sound insulation. This is a general quality rule. In other words, in order to achieve sound insulation effect, you can use a rigid board with a thickness of 4cm as a door panel or pour cement into the door panel to improve the quality and achieve higher sound insulation effect. But the sound insulation effect is achieved, but the weight of the door panel does increase the burden on the door foot. If the hinge is not fully loaded, the door panel is not easy to open and close, or even damaged. Therefore, unless necessary, sound insulation is needed.
