标准摘要
[中文适用范围]: 本文件规定了如何评估用于室内使用的屏风、家具和单个物体的吸音性,并规定了地板屏风声音衰减的评估。 它还规定了在什么情况下办公室、学校和其他公共空间的各种室内产品被视为平面吸收器或离散的单个物体。 被视为单个物体并打算用于室内使用的产品根据 ISO 354 进行测量,并通过其等效吸声面积或倍频程物体吸声系数进行评估。 本文件定义了室内产品和单个物体,并包含有关单个物体的测量和评估的附加信息。 本文件规定的吸声率可用于计算: a) 房间内的混响时间特性; b) 使用射线追踪软件的房间声学参数。 [外文原描述]: This document specifies how screens, furniture and single objects intended for interior use are assessed with regard to sound absorption and specifies the evaluation of sound attenuation for floor screens. It also specifies under which circumstances various interior products for offices, schools and other public spaces are considered as plane absorbers or as discrete single objects. A product considered as a single object and intended for interior use is measured according to ISO 354 and evaluated by its equivalent sound absorption area or object sound absorption coefficient in octave bands. This document defines interior products and single objects and it comprises additional information regarding measurements and assessment of single objects. The sound absorption as specified in this document can be used to calculate: a) reverberation time characteristics in rooms; b) room acoustic parameters using ray tracing software.
