摘要
本文借鉴现有规范,首先对国内外相关技术规范和测量方法进行调研分析,确定影响隔声量测量和评价结果的关键因素,然后研究建筑构件隔声量的实验室测量方法,获取与现场测量相同墙体结构测量数据。将实验室测量、小空间现场测量和超大墙体空间现场测量三种墙体类型的检测结果进行分析比对,提出一套与实验室和小空间现场测量结果相一致的超大墙体的测量和评价方法,以此为大型影厅和摄影棚的设计和测量评估提供一定借鉴,同时有利于进一步规范和科学评估隔声量的测量方法和结果。
Refers to existing standards,the paper first conducts research and analyzes on domestic and foreign standards and measurement methods,determines the key factors that affect the measurements and evaluation results of sound insu⁃lation.Then the paper studies the laboratory measurement methods of the sound insulation in building elements,obtains measurement data for walls in structures the same with real scenes.The paper then analyzes and compares the testing re⁃sults of three types of facades in laboratory measurements,in small facades room,and in super large facades room,thus proposes measurement and evaluation methods for super large facades that are consistent with laboratory and small fa⁃cades measurement results.The paper provides reference for the design and measurement evaluation of large auditori⁃ums and studios,it is also beneficial for standardizing and scientifically evaluating the measurement methods and results of sound insulation.
