Acoustics — Measurement of sound absorption in a reverberation room ISO 354:2003

Publication date:   May 14, 2003

Scope

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.
