room design help

thanks for all the help, I was away for a few days , hence delay.I contacted Rives but their preprinted form is for someone that has a room and not for a new room, I filled it in as best i could but it looked ridiculous so I threw it in the bin. Maybe an email to Ethan is the best. Im stuck with about 300 sq ft max and a height of 8 ft or a little more, so what I want is a suggestion as to the best golden dimension and some ideas on what to build in to the construction. I read acoustic 101 , but there is a lot of really really detailed stuff, which is beyond my grasp. willie

In my experience, your room should be about 16' wide. Mine is appx. 14.5' and seems a little narrow. Double sheetrock and a weatherstripped solid wood door is invaluable. For the ceiling I would opt for the more expensive specialty drywall that is available. There is also a barrier that you can use between the layers of sheetrock that will increase the wall mass without the bulk but I forget what that product is. A nice troweled-on layer of silicone between the sheetrock layers should also help. A length of about 21' should suffice for most applications. If you build your bass traps into the corners from the start it will save you money on treatments. An effective way is to kind of round the room corners with sheetrock and if you can get insulation into that void space created helps tremendously. Just a few thoughts.

Willsandbills, Rives also designs new rooms. You mentioned that your ceiling height may be 8 feet. If so, you do not want a 16' width as Twc recommended. When a dimension is a multiple of another, your standing wave problems generally increase. Since you have an opportunity to build a listening room from scratch, why not maximize the acoustics by consulting an expert.

I am now in correspondence with Ethan and hopefully he will design the room and supply the various bits that he has designed.thanks all,

Don't forget the ceiling measurements with the golden ratio! The ceiling is usually the limiting factor and equally important. For example if the ceiling is 8 feet high, then the length and width of the room must be 13 by 21 feet. If the ceiling is 9 feet, then the other measurements must be 14.5 by 23.5, etc.
