Our society was asked to create a big rehearsal room for a 100+ man wind instrument orchestra. The restraints were to leave the wall architecture untouched, and use a material with a wood finish.
The room had to have a quite strict reverberation time requirement( between 1,2 and 1,5 sec) and a good St1 value, also it had to sometimes accommodate an audience so acoustic parameters for it had to be at least decent.
We managed to produce a good simulation thanks to Odeon. Auralisation were produced for the client, and it was very good to make the client feel directly the difference in acoustic, it gave strength to our modification proposals , and made more complex parameters reasily understandable, in the end the client was capable of fully understanding the enhancement choices we made and their effect on the acoustic of the room.
