声学

[中文适用范围]： 本文件规定了一种测量建筑物内安装的服务设备在房间内产生的声压级的工程方法。本文件专门涵盖卫生设备、机械通风、供暖和制冷服务设备、电梯、垃圾槽、加热设备、鼓风机、泵和其他辅助服务设备以及电动停车场门产生的声音的测量。它还可以应用于测量建筑物内其他类型设备或活动产生的声音，例如体育设施或餐厅产生的噪音。本文件不包括在建筑物内产生空气传播或地面传播噪音的外部声源产生的噪音的测量。这些方法适用于体积约为 300 立方米或更小的房间，例如住宅、酒店、学校、办公室和医院。这些方法不适用于大型礼堂或音乐厅的测量。 [外文原描述]： This document specifies an engineering method for the measurement of sound pressure levels in rooms from service equipment installed in the building. This document covers specifically measurements of sound from sanitary installations, mechanical ventilation, heating and cooling service equipment, lifts, rubbish chutes, heating devices, blowers, pumps and other auxiliary service equipment, and motor driven car park doors. It can also be applied to measurements of sounds from other types of equipment or activities within the building, e.g. noise from sport facilities or restaurants. The measurement of noise from external sound sources generating air-borne or ground-borne noise in the building are not included in this document. The methods are suitable for rooms with volumes of approximately 300 m 3 or less for instance, in dwellings, hotels, schools, offices and hospitals. The methods are not intended for measurements in large auditoria or concert halls.
