2. (acoustic panel)According to the location of sound insulation, it can be roughly divided into indoor sound insulation and outdoor sound insulation. For example, indoor sound insulation includes: walls, building surfaces, ceilings, and other characteristics that need sound insulation. The sound insulation of building surfaces and underground buildings is also input into the indoor sound insulation part; The main items of outdoor sound insulation include sound insulation of outdoor walls and other outdoor sound insulation projects.
3. (acoustic panel)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 method using various sound insulation materials for sound insulation. Sound insulation materials with different performances shall be used in sound insulation, and their respective characteristics shall be used in combination in sound insulation, so as to give full play to the advantages of their respective sound insulation materials, so as to improve the overall performance of sound insulation and achieve the effect of "combination of rigidity and softness, multi-channel sound insulation and comprehensive protection".
Structural self sound insulation refers to a sound insulation method that adopts a certain form or method to carry out structural self sound insulation or combined with blocking sound transmission. For example, sound-absorbing cotton, sound-absorbing board and other materials are used to absorb and analyze the sound continuously, so as to weaken the transmission path of the sound and change the range of sound transmission at the same time.
