Sound barrier with sound insulation and efficiency improvement functions
The invention relates to a sound barrier with sound insulation and efficiency improvement functions. The sound barrier comprises a sound insulation unit, a sound absorption unit and a supporting frame. The sound insulation unit has light transmission and is provided with a first surface facing a noise source and a second surface opposite to the first surface; the supporting frame is arranged on the periphery of the sound insulation unit, and the sound absorption unit is fixed to the edge area of the first surface of the sound insulation unit in a protruding mode through the supporting frame and shields at least part of the area of the supporting frame. The supporting frame is used for arranging the sound absorption unit, the sound absorption unit shields at least one part of area of the supporting frame, light transmission is not affected, the stability of the structure can be guaranteed, meanwhile, the sound absorption unit can capture reflected sound waves of the sound insulation unit, the supporting frame is partially shielded, the reflection area of the sound waves is reduced, the noise reduction effect is further achieved, and the noise reduction effect is improved. And the sound barrier can meet the use requirements of light transmission, noise reduction, efficiency improvement and stable structure at the same time.
本申请涉及一种隔声增效的声屏障，包括隔声单元、吸声单元及支撑框架；隔声单元具有透光性，并具有用于朝向噪声源的第一表面与背向第一表面的第二表面；支撑框架设置在隔声单元的四周，吸声单元通过支撑框架凸出地固定在隔声单元的第一表面的边缘区域，并遮挡支撑框架的至少一部分区域。本申请利用支撑框架设置吸声单元且吸声单元遮挡支撑框架的至少一部分区域，不会影响透光并能够保证结构的稳定性，同时，吸声单元可捕捉隔声单元的反射声波，支撑框架被部分遮挡而减少对声波的反射面积，起到进一步降噪效果，使声屏障同时兼顾透光、降噪增效、结构稳定的使用需求。
