Room acoustics tool added to Finnish Standard SFS 5907
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.
