The simplest and most practical sound insulation method is to use sound insulation board.
Sound insulation board is a section that acts on sound insulation effect. There are building sound insulation and structure sound insulation classification. Sound insulation board is not all frequencies of sound can be blocked, objects have natural resonance frequency, sound close to the resonance frequency of objects, the sound insulation effect of sound insulation board is obviously reduced.
Sound insulation board has the difference between air insulation and vibration sound. Air sound insulation board, that is, the board that blocks the sound transmitted in the air. Vibration sound insulation panels are boards and systems that block sound transmitted in rigid components (such as reinforced concrete integrated houses).
Type
The classification of building sound insulation engineering can be classified according to the location of anacoustic, the method of anacoustic, the adopted sound insulation materials and varieties.
1. According to the classification of civil engineering, it can be divided into building sound insulation and structure sound insulation.
2. Classified according to the location of anacoustic, it can be roughly divided into two categories: indoor sound insulation and outdoor sound insulation. For example, indoor sound insulation includes walls, building surfaces, ceilings, and other building surfaces that require anacoustic characteristics, and underground building sound insulation is also input into indoor sound insulation; the primary items of outdoor sound insulation include sound insulation of open-air walls and other outdoor sound insulation projects.
3. According to the classification of anacoustic methods, it can be divided into composite sound insulation and structural self-sound insulation. Composite Sound insulation refers to a new sound insulation method sound insulation materials by using various anacoustic. Sound insulation materials with different properties are adopted in sound insulation, and they are used together in sound insulation by taking advantage of their own characteristics. In order to improve the overall performance of sound insulation materials and achieve the combination of rigid and soft, multi-channel sound insulation, comprehensive protection effect.
Structural self-sound insulation refers to a sound insulation method that adopts certain forms or methods to construct self-sound insulation or combines to block sound transmission. For example, materials such as sound-absorbing sponge and acoustic panel are used to continuously absorb and analyze sound to weaken the transmission path of sound and change the transmission range of sound at the same time.
Extended Data: Main features
Main features of sound insulation board: on the premise of ensuring sound absorption and sound insulation effect, it is characterized by simple manufacture and installation.
1. Large sound insulation capacity: the average sound insulation capacity is 30dB. (Condition sound-absorbing sponge 48K, thickness 95 × height 500 × length 1000-3000)
2. Weather durability: The product has water resistance, heat resistance, UV resistance, and will not reduce performance or abnormal quality caused by rain temperature changes. The sound insulation barrier of the product adopts endurance plate, galvanized endurance plate, glass wool, and H steel column surface galvanized treatment for more than 15 years.
3. Beautiful sound insulation board: you can choose a variety of colors and shapes to combine, coordinate with the surrounding environment, and form a magnificent landscape.
4. Sound insulation board economy: Assembly construction can improve work efficiency and shorten construction time, which can save construction cost and labor cost.
5. The sound insulation board is convenient: it is installed in parallel with other products, easy to repair, and easy to update.
6. Sound insulation board is safe and sound: both ends of acoustic panel absorber are connected and fixed with steel wire rope 6.2 to prevent secondary damage and cause loss of personnel and property.
7. Convenient sound insulation board: acoustic panel series products have the characteristics of light weight, and the mass of square meters is less than 20 kilograms, which can reduce the load-bearing load of elevated light rail and elevated road and reduce the structural cost.
It is recommended to use thick double-layer curtains instead, which is more realistic and has good sound absorption effect. It is not recommended to change the Casement glass. One is that the profiles are not universal, and the other is that the cost of replacing new ones is too high!
Add sound insulation cotton to the wall. Advantages: good sound insulation effect, beautiful and practical, space saving, and certain fire prevention effect.
Add foam or sponge to the wall. Advantages: good sound insulation effect and common cost. Disadvantages: it occupies a large area of wall space and is not fireproof.
Add corrugated cardboard to the wall or hang it with a thickness of cloth curtain. Advantages: sound insulation effect is common and cost is low. Disadvantages: not beautiful, not setting fire, easy to fall off.
Advantages of professional sound insulation glass: good sound insulation effect and beautiful appearance. Disadvantages: high cost.
Double-layer glass for sound insulation advantages: good sound insulation effect. Disadvantages: high cost, complicated craftsmanship, not neat.
Sound insulation use composite door, advantages: sound insulation effect is good. Disadvantages: high cost.
Create a room in room. Advantages: excellent sound insulation effect.
