A soundproof plate is a plate that acts on the sound insulation effect. There are building sound insulation and structure sound insulation classifications. Sound insulation board not all frequencies of sound can be blocked, the object has a natural resonance frequency, close to the object resonance frequency of sound, the sound insulation effect of the sound insulation board is significantly reduced.
The sound insulation board has the difference between air and vibration sound. Air sound insulation board, that is, the board that blocks the sound transmitted in the air. Vibratory sound insulation panels are panels and systems that block the sound propagating in rigid components (such as reinforced concrete integrated houses).
1. According to the classification of civil engineering, it can be divided into two types: building sound insulation and structure sound insulation.
2. According to the location of sound insulation, it is roughly divided into two categories: indoor sound insulation and outdoor sound insulation. For example, indoor sound insulation includes: walls, construction surfaces, ceilings, and other characteristics that need sound insulation, building surfaces, and underground building sound insulation are also input indoor sound insulation parts; The main outdoor sound insulation projects include outdoor wall sound insulation and other outdoor sound insulation projects.
3. According to the classification of sound insulation methods, it can be divided into composite sound insulation and structural self-sound insulation. Composite sound insulation refers to a new sound insulation practice using various sound insulation materials for sound insulation. Soundproofing materials with different properties are used in soundproofing, using their respective characteristics to compound in soundproofing, and then play the advantages of their soundproofing materials to improve the overall performance of soundproofing, so as to achieve the effect of “rigid and flexible combination, multi-channel soundproofing, comprehensive protection”.
Structural self-sound insulation refers to a sound insulation practice that adopts a certain form or method to construct self-sound insulation or combined with blocking sound transmission. Such as the use of sound-absorbing cotton, sound-absorbing board, and other materials, and the use of continuous sound absorption, to reduce the transmission path of sound, while changing the range of sound transmission.
In order to achieve a good sound insulation effect, the installation method of the sound insulation board must be very simple, otherwise, it is difficult to achieve the ideal sound insulation effect.
