摘要

研究了广州大剧院多功能剧场的双层通风管道声学特性.基于对双层通风管的理论分析，利用空调系统在不同负载下运行而测得的室内噪声级，深入探讨内层为吸声材料的双层通风管道的消声性能对室内声环境的作用.实测结果表明：剧场的噪声级水平满足设计的声学要求.各测量位置的噪声级存在不显著的差异.随空调系统负载增加，室内噪声级的增幅较小.双层通风管道的使用能确保剧场拥有一个舒适的声环境.

Abstract

It presented the acoustic property of double-decked duct in Multi-functional Theater. It analyzed the muffling function of double-decked duct to find out its role in the indoor acoustic comfort

using the indoor noise measurement data under different loads of air conditioning operation. It showed the acoustic design was satisfied by measurement result. Noise levels in each measurement points and times were different

but not significantly. As operating load enlarged

the net increase of noise was small. Then the muffling of double-decked duct ensured the acoustic comfort of the theatre.
