Unfortunately, the current proposal is without any treatment....
But, because of my remarks, we did had a meeting with the architect present.
I drove them around and showed them existing places, rehearsal rooms,etc. To give an idea how rooms can sound.
Afterwards there was an informal meeting I set up, with a retired acoustician, who's work I know really well. All this just to explain the basics & to get a fresh perspective, steer away from the current problematic issues.
I saw the architect taking a lot of notes.
Can only hope, that the plans will be more promising & that in the future, they will be willing to pay for proper (calculated) advice.
In any case, I want to thank you guys, for confirming my suspicions.
kindest regards,
Frank Duch
