And what's the easy technique to appliy those numbers against a door ?
Gripfill' filler adhesive.

Listening to what the supplier says, then subtracting somewhat.
For the rest testing.
It's hardly possible to calculate this correct.
A gap is as well a filter as a resonant channel.
On a good door one uses good rubbers and better two (if you use only one door)
And mostly the treshold is the most sensitive part.

Eric is right on with this - for professional studio doors i use 2 good (General Motors) rubber gaskets - plus a magnetic weatherstrip - and work my butt off on the door bottoms to try to get a good seal.

Paul - i understand what you're doing - but we could not do anything like that in a commercial establishment here - we would not come even close to meeting the requirements for the Life Safety/Building codes - or the "American with Disabilities Act" (ADA) - so for us this isn't a code compliant installation - and that is always an issue.
But it is a beautiful thing you've constructed.

The multiple seals scare me because I'm worried that it'll make the door hard to open and close. I have two doorways that will see a fair bit of traffic, although not as much as a professional studio.
