Work on my music room is not to start until a year or so from now (the missus thinks
having a decent living room & bedroom is a more urgent matter...), but I am so curious
about the nature of my corners. I've read tons and tons of material (mainly this forum and
several other sources), and understand quite well the principles of accoustics, bass
traps, mid and high freq absorbtion, and diffusion, but my question concerns a special
case of corner bass trapping.
My room will be in the attic, with say 50cm hight
of walls all around, and from there up the roof sloping inwards on three sides. The angle
between wall and roof slope = 130°. Equally, instead of having 4 vertical corners between
walls, I have 2 "sloping" corners where the roof sides meet; these also have an angle of
around 130 to 135° (impossible to measure decently due to supporting construction).
Now all corner bass trap articles assume 90° corners, and most advise to tackle
corners first as these give the strongest bass buid up. But what about the angle: does a
130° angle give birth to as much bass build up as a 90° one, or can it be regarded as
something more toward a flat surface?
I do know that just walls also need bass
trapping treatment to get the best results, and I intend to trap these wider corners
anyway (possibly with two panel traps each side of the corner, which was indicated in one
article as a space saving alternative to the regular corner trap). So the question may
eventually be academic. But the subject just interested me, so if anybody can fulfill my
lust for knowledge...
