About this Event

Instructor: Ben Cazzolato [email protected]

This is a face-to-face workshop. Please do not book unless you are able to attend in person.

This test method covers 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 based on the following standards: ASTM C423 and ISO 354. These methods both use the decay rate measured in the reverberation room to characterise the absorption of the test specimen.

The facilities used will be the Reverberation Chamber in the AVL, a Bruel and Kjaer 2270 SLM, and a Bruel & Kjaer OmniPower Sound Source.
