每个人都希望有一个属于自己的安静舒适的房间，隔音板成为了他们一个很不错的选择，一般的物体都具有隔音效果，但是我们把平均隔声量(在无限大的空间中，声源与Put a piece of unlimited material between the measured points) more than 30DB of boards to be called the sound insulation board.The sound insulation board is generally high -density material.Here are the information, principles, materials, and installation related information of the sound insulation board.
Sound insulation board material
The sound insulation material refers to a type of material, component or structure that can block sound transmission or weaken transmission sound energy. It is characterized by higher quality density, such as steel plates, lead plates, concrete walls, brick walls, etc.The more common people are solid bricks, steel bars mixed dirt walls, wooden boards, gypsum boards, iron plates, sound insulation felt, fiber boards, and so on.In strict sense, almost all materials have sound insulation, and the difference is that the size of different materials is different.The same material has a relatively large change in the amount of sound insulation due to different surface density.The principle of sound insulation follows the law of quality is that the larger the density of the unit dense surface of the sound insulation material, the greater the sound insulation, and the proportional proportion of the surface density and the sound insulation amount.
Principles of sound insulation panel effect
A kind of transmission of sound is called cross -proof dissemination.That is, enter another medium from the critical contact surface of one medium through the two media. At this time, the transmission of sound energy is the transmission of vibration amplitude.When the interval is transmitted, the larger the density of the two media, the greater the loss of sound energy.In practical applications, air is the activity space in the normal state of human beings. Therefore, the more different materials that are different from the air density are generally high -density materials (the materials that are much lower than the air density are much more than the vacuum, which is not really much)Can be regarded as sound insulation materials.The higher the density, the better the sound insulation effect.The plate made of such materials is called a sound insulation board.The sound insulation method is to use a certain sound insulation material to isolate the sound source from the surrounding environment, so that the noise of its radiation cannot be spread directly to the surrounding area, thereby achieving the purpose of controlling noise.The essence of sound insulation is the sound radiated from the sound source as much as possible. Common measures include sound insulation materials and sound insulation structures.
Sound insulation board price
The quality and thickness of the sound insulation board on the market are also different. Generally, the thickness of the polyester fiber sound -absorbing board is 90 yuan per square meter.There are different prices and differences in the price levels of various places.Let ’s take a look at the price of different materials, the prices of the sound insulation boards of different materials, the prices of different brands.Zhurui soundproofing board polyester fiber 42/square meter Xinde soundtracking board South Rock wool 150/square meter home sailing sound plate density board 55/square meter Zhuohong sound steel 374/square meter Xinboo soundtrack panel cork 180/square meter 180/square meter
