标准摘要
[中文适用范围]： 本国际标准规定了一种在混响室中测量用作墙面或天花板处理的声学材料的声吸收系数，或测量家具、人员或空间吸声体等物体的等效吸声面积的方法。本方法不打算用于测量弱阻尼谐振器的吸收特性。所获得的结果可用于比较目的，以及用于房间声学和无噪声控制的计算设计。 [外文原描述]： ISO 354:2003 specifies a method of measuring the sound absorption coefficient of acoustical materials used as wall or ceiling treatments, or the equivalent sound absorption area of objects, such as furniture, persons or space absorbers, in a reverberation room. It is not intended to be used for measuring the absorption characteristics of weakly damped resonators. The results obtained can be used for comparison purposes and for design calculation with respect to room acoustics and noise control.
