摘　　要：目前使用较多的轻质隔墙体的隔声量普遍偏低,难以满足人居声环境的相关要求。分析表明,影响轻质隔墙体隔声能力的因素是面密度低、共振现象、吻合相应以及声桥等。改善轻质隔墙体隔声性能的途径有采用"板面-空腔-板面"结构,以及采用不同材质和面密度的墙板组合,中间空气层添加吸声材料,两侧板之间设置减震装置等措施。The sound insulation effect of the current commonly used lightweight wall is generally low,and it is difficult to meet the relevant requirements on living sound environment. The analysis results show that mainly factors affecting sound insulation capability include low surface density,resonance phenomenon,coincidence effects and sound bridges,etc. Accordingly the approaches to improve the sound insulation performance of lightweight wall are put forward., using the ＂mass-air-mass＂ structure, or using composite wall panels of different materials and surface densities, with intermediate airspace filling sound-absorbing material and shock absorber setting between two side plates.
