hi
I have the possibility to make a new listening room for my stereo.
the room will be established in my old barn.
The barn is made of solide brick walls (not wood) with a 8 feet high
cieling that consists of small arcs each approx. 3 feet wide.
The room can be up to 17 feet wide and is 30 feet long.
That would be kind of a normal room with standing waves between the
two set of opposing walls. But hopefully not between the cieling and
the floor because of the arced cieling.
What if I made one wall 3 feet smaller. the wall behind the speakers
would be 17 feet. The wall behind the listening position would be 13
or 14 feet. The two side walls would still have the same length (There
would not be any 90 degree corners in the room) but they would not be
parallel anymore.
I would still have a standing wave between the two end walls but at a
low frequencie ( 19 hz ) and harmonics of that.
would it have a nice acoustic/sound??????
Will it not have any sound at all?
Can a room have a boring sound?
How does a round room sound? A triangular, hexagonal etc.?
Is there anything perfect?
Anything close to perfect that you can actually build?
best regards
Uwe

Re: another shape than rectangular
Certainly, rectangular rooms are the easiest framing wise, and one can find any number of magical formulas for dimensions and treatment regimens borrowed from recording studios. But if you have the freedom to design outside of those parameters, rooms with the fewest parallel surfaces can manage will tend to cause far fewer acoustic problems.
Of course that's easier said than done.
At the very least if the ceiling can be raised above 10ft and lofted to cathedral angles you can mitigate much of the mid-bass floor bounce.
My main listening room is a teeny former basement bedroom, with a lower than usual ceiling and only slightly wider than 8ft. It's far easier to build a speaker that sounds good in a larger room, than to get this little room out of the way of even a small bookshelf or stand-mounted 2-way or fullranger.
OTOH, a buddy of mine has a very nice room that is not gigantic in terms of total floor space, but has a very highly vaulted ceiling (from just over 6ft on the front wall, to almost 17ft on the back wall) - floor to ceiling reflections are not an issue, and the room is wide enough ( L-shaped between 16 and 32ft) that the lowest frequencies in any of the music we ever listen to are quite effortless.
