Annex H is now added to the original version of the Finnish Standard SFS 5907, previously described in Ecophon Acoustic Bulletin and initially published 2004.
Annex H is informative and estimates the amount of Class A resp. Class C absorption material needed, as a percentage of the surface area of the space, with respect to various heights and reverberation times.
SFS 5907 uses reverberation time as unique descriptor of the room acoustics.
The conversion table is based on a Sabine model and applies therefore to simple, diffuse rooms.
