I am not quite as surprised by the results although in the perfect model doubling the measurement on the rectangle would cause problems. However what we don't know is the materials in the room,whether your measuring a blank room, ect. The one question concerning what's above the ceiling is the right one. Acoustical applications can make all the difference in the world. In my app. I paid a lot of attention to what went behind the wall,ceiling,and floor. Despite things I couldn't change about an existing configuration the result with regard to resonance and other issues was very satisfying.
Resonant modes and taming the room
I measured my listening room and calculated the room modes, and graphed them today. I was trying to determine if/where the resonant frequencies were too closely grouped. Ultimately I was pleasantly surprised by the fact that I do not show any serious problems.
My question though is, how can I tame the room to eliminate the areas of congestion in the modes I am experiencing? Are there differing approaches based on the frequency of the modes?
My room is L 22'-5" x W 12'-10" x H 6'-5". I was concerned about the low ceiling, but it appears to help in this application rather than hinder.
Any insight you might offer would be appreciated.
