中文摘要:
      营造健康舒适的室内环境,对室内声舒适性有明确的要求。空气传声途径的隔声是反映建筑物声学质量最重要的物理量,控制建筑室内噪声水平已经成为室内环境设计的重要工作。本文研究了轻质墙体的隔声性能,重点分析了墙体中龙骨的类型、龙骨间距、空腔填充材料类型、填充材料厚度、面板层数和质量等对轻质结构墙体隔声性能的影响。测试结果表明,扩大独立面板尺寸,增大龙骨间距,墙体空腔填充岩棉或玻璃棉,增大面板层数或提高面板质量,避免结构性连接,对于优化改善双叶结构轻质墙体的隔声性能有积极效果。
英文摘要:
      To create a healthy and comfortable indoor environment, there are clear requirements for indoor acoustic comfort. The sound insulation of air-borne acoustic pathway is the most important physical quantity reflecting the acoustic quality of buildings. Controlling the indoor noise level of buildings has become an important work of indoor environment design. In this paper, the sound insulation performance of light-weight wall is studied, and the effects of stud types, stud spacing, cavity filling material types, filling material thickness, number of panel layers and panel quality on the sound insulation performance of light-weight structure wall are analyzed. The test results show that expanding independent panel size, increasing the stud spacing, filling wall cavity with rock wool or glass wool, increasing the number of panel layers, improving panel quality and avoiding structural connection has a positive effect on optimizing the sound insulation performance of the light wall with double-leaf structure.
