ISO 354 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.

ISO 354 规定了测量用作墙壁或天花板处理的声学材料的吸声系数的方法，或混响室中物体（例如家具、人或空间吸声器）的等效吸声面积的方法。 它不适用于测量弱阻尼谐振器的吸收特性。 获得的结果可用于比较目的以及有关室内声学和噪声控制的设计计算。
