Room modes accuracy with angled ceiling

Hi all,

Long time lurker here, I've recently moved into a house with a potentially great room for music making. The dimensions are:
4.76m L x 2.70 W x average of 2.77 H (2.34 at the short end, 3.2 on the high end).

I've identified the room modes using amroc and done a REW waterfall plot which shows the strongest modes (71HZ & 105Hz) more or less correlate with amroc's predictions.

From my reading, room modes are difficult to predict with angles however from my initial tests it seems that they were ballpark accurate.

As I'm planning on building pressure based absorbers, would it be 'safe' to carry on with trapping according to the pressure zones?

Many thanks!

NJice work!

Use the waterfall results. That looks like ~53, 75 and 110 Hz.

To others reading his thread: by 200 Hz the pattern is fairly diffruse and porous absorption is the logical choice
