Your English is excellent - much better than my German, I must say.
I am not good at reading plans or sections so I was wondering where the actual ceiling was located. It now seems obvious that it is the line I have highlighted in blue on the section and not the line highlighted in red.
I am also wondering about the details in the studio section that are labeled "11". It looks like conduit...?

I was asking if the soffits are to be solid gypsum or wood rather than wood on the bottom and fabric up the inside face as we so often see. But as you have explained, they are solid and as they are sufficiently thin they would act as membrane absorbers. Seems like a very clever approach.

I searched with Google for the Pawel absorbers but couldn't find any information on them. I am sure there are many products available in Europe that can't be found in North America.
Thanks for the ceiling reflection plan. Does the wood ceiling have a lot of perforation or might it be just the circles indicated? I am guessing that those are lighting fixtures. With the helmholtz wall panels and the wooden ceiling the room will look great.

I think that's what makes the internet so great - you get all this information for free, but at some point you have to give back if you have something you can share to make it work... |
Well, thanks for answering so many of my questions. So much of what reads regarding room design and acoustics is confusing and often contradictory and so it is great to see the process so clearly defined and so well articulated. I have been getting back to reading the forums (now that my young son sleeps a bit more) over the past while and it is again proving to be a terrific resource.
