EN ISO 354 Acoustics - Measuring Sound Absorption in a Reverberation Chamber

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 354 testing. EN ISO 354 specifies a method of measuring the sound absorption coefficient of acoustic materials used as wall or ceiling applications in an echo chamber, or the equivalent sound absorption area of ​​objects such as furniture, people or space absorbers.

EN ISO 354 Acoustics - Measuring Sound Absorption in a Reverberation Chamber

Weakly damped resonators are not intended to be used to measure the absorption properties. The results obtained can be used for comparison purposes and for design calculations related to room acoustics and noise control.

When a sound source operates in a confined space, the level at which reverberant sound accumulates and the subsequent reduction of reverberant sound when the source is stopped are governed by the sound-absorbing properties of the boundary surfaces of the air filling the space and objects in space. In general, the proportion of incident sound power absorbed at a surface depends on the angle of incidence.

In order to relate the reverberation time of an auditorium, office, workshop, etc. to the noise reduction to be achieved by an absorptive treatment, knowledge of the sound absorption properties of surfaces is required for all angles of incidence, usually in the form of a suitable average.
