电影行业超大墙体建筑隔声量的测量研究
Research on measurements of sound insulation in super large facades of film industry
摘要
Abstract
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.关键词
