Room Treatments - How?

room treatment would apparently be one of those areas where 'art meets science'.
To get a definite answer is quite impossible. You don't know everything you'd need to know and I doubt anyone knows how it all works to get a 'DO THIS' to get THAT result kind of answer.
That there are general principles and a lot of knowns is a YES. That an equation or simple system approach will hit the 'bullseye' is probably NO.

Even designing a large concert hall or recital hall from scratch will require a bit of fine-tuning when it's done. To do a retro on an existing space, I'm thinking, would be more difficult. These guys use extensive computer modeling and have complete design and materials control....from first shovelfull of dirt to the last dab of paint.

Another helpful group is Rives Audio.

My connection to Rives? I bought a calibration CD from them. It is matched to the RadioShackup analogue SPL meter.

Another room acoustics question with no information about the room or system.

Give me more information about your room and your system and I will see what I can do to help.

Rrog,

PM sent. I appreciate your willingness to help. But please note that I was not asking for someone to design a solution for me. I was asking how to turn an analysis into a room design. Thanks again.

I'm in line with what Magfan said. I think you either need to outsource this or DIY and if so, get going with understanding what acoustics is about. I went for the latter as I was intrigued and enjoy understanding what is going on. There is a lot to learn and I'm only starting, but I kind of know the basics and built some treatments and made changes successfully.

If you want to understand acoustics I recommend you read the Master Handbook of Acoustics by Alton Everest (you really need this one), and Sound Reproduction by Floyd Toole (a good complement to the first one).

As has been noted, the best acoustic designer in the world still never can tell what the exact results would be. They take theory and materials and then try to apply it. You need to do the same thing until your ears tell you it is 'better sound'. One of the most neglected areas of treatment is the ceiling of most rooms. The application of 'wave theory' is a must. Armstrong makes some interesting treatments in this area and has some great 'white' papers that explain what it is all about.
