Frequency-adjustable sound absorption and insulation light composite board and manufacturing method
The invention discloses a frequency-adjustable sound absorption and insulation light composite board which comprises a perforated board, the perforated board is an open box-shaped body provided with a frame, a sound absorption layer, the damping layers, a middle thin board, a sound insulation layer and a sound insulation board are sequentially arranged in the box body from bottom to top in a tightly attached mode, the sound insulation board is fixedly connected with the frame of the perforated board, the damping layers are bonded to the plate face, opposite to the sound insulation layer, of the middle thin plate in a periodic arrangement mode. The sound absorption and insulation light composite board is simple in structure, diversified in form and convenient to manufacture, particularly, the periodic damping structure greatly reduces the surface density and cost of the sound absorption and insulation light composite board compared with a traditional laying full-damping structure, and the resonance and coincidence effect of components are restrained through laying of periodic damping. The periodic arrangement mode of the damping layers realizes sound insulation of noise sources with different frequencies.
本发明公开了一种频率可调的吸隔声轻质复合板，包括穿孔板，所述穿孔板为设置有边框的敞口盒状体，在盒体内自下而上依次紧贴安置有吸声层、阻尼层、中间薄板、隔声层和隔声板，其中，所述隔声板与所述穿孔板的边框固定连接，所述阻尼层采用若干周期性排列方式粘接于所述中间薄板与所述隔声层相向的一板面上。本发明结构简单，形式多样，便于制作，尤其是周期性阻尼结构，相较于传统敷设全阻尼结构，大幅度降低了吸隔声轻质复合板的面密度与成本，周期阻尼的敷设抑制了构件的共振及吻合效应。阻尼层的周期性排列方式实现了对不同频率的噪声源的隔声。
