By taking reasonable distribution: dynamic and static separation of noise source, noise control facilities, from the source to improve the sound insulation, sound absorption and reduce the reverberation envelope structure, damping measures to reduce noise and other noise control measures, which can meet the new requirements. Key words: ing separation ; Source control ; Sound insulation enclosure structure ; Noise control measures 一、前言随着我国经济、科技的发展,民用建筑所配置的机电设备都越来越多,使得噪声源不断增多。同时, 随着经济水平的提高,人们对提高包括声环境在内的生活环境质量的要求不断提高,人们的噪声容忍度也不断下降。作为影响室内声环境主要噪声源, 机电设备的噪声影响评价标准由三类相关标准交叉覆盖, 机电产品、建筑室内、环境保护等噪声相关标准所具有不同的侧重点, 造成同一机电设备噪声对人们生活、工作、休息的的影响等方面的界定上存在差距和歧义。由此引发诸
