Scope

本文件描述了使用声压法测定外墙构件(构件法)和整个外墙(外墙法)的空气声隔声性能的方法。
本文件适用于容积为10 m3~250 m3的房间中50 Hz~5 000 Hz频率范围内的测量。
测试结果能用于量化、评估和比较空气声隔声性能,无论房间内是否有家具,声场是否近似于扩散场。测得的空气声隔声性能与频率有关,根据GB/T 50121和ISO 717-1中给出的方法能将其转换成表征声学性能的单值评价量。
构件法用于测定外墙构件,如窗户的隔声量。最精确的构件法是用扬声器作为人工声源,采用现场交通噪声作为声源的方法测量精确性略差。外墙法旨在确定实际交通条件下室外和室内的声级差。最精确的外墙法是利用实际交通噪声作为声源。当室内接收到的交通噪声级不够高时,需采用扬声器作为人工声源。表1给出了这些方法的概述。
