Acoustic treatment for 'triangular' room...

Question Acoustic treatment for 'triangular' room...

It looks like I'm going to be moving home and my edit suite is going to be in a loft room in the roof. It is a weird shape so I'm wondering how best to treat it.

The room is 30' long, about 11' wide and the ceiling is only 7' high in the middle and slopes down either side (i.e. roof shaped, so the room has a triangular cross-section). Based on cursory 'clap' checks the room is not lively.

Any hints would be very gratefully received.

Many thanks.

Can you post some pictures?

My first guess without seeing it would be that you will want a fair amount of absorption on the sloped area. The "bottom sides" of the triangle (fairly unusable I assume from the height) would be a good space for lots of fuzzy bass trapping.

Set up your speakers at one end, firing toward the other end 30 feet away. You'll need plenty of bass traps, and also absorption under the peak and at reflection points. That room is very long. Do you need the full length? Can you make a wall partway back?

Thanks both for your responses.

@Smithcok - no, I'm sorry I don't have any photos yet. Would the bottom angles of the triangle need to be bass trapped all the way down, or at random points to diffuse?

@Ethan - I don't understand what you mean by 'under the peak' - could you please clarify? Do you mean middle of the ceiling (top angle of the triangle)?

Many thanks.

Below is the famous photo of my home studio ceiling. heh

My ceiling is 12 feet high at the peak, so I have plenty of room to hang stuff below the peak. In your case you'll put traps flat on the ceiling rather than lower the height even more. But the concept is the same - absorption under the peak to avoid the focusing effect.

I'd agree that it would be good if you could wall off a portion of it so it's not SO long compared to wide.

On the slants, you can also use some diffusion to make it sound a bit large than what it is.

In addition to doing the 'corner' at the ceiling peak, you could easily use some verticals to chop off the floor/wall corner and get a lot of nice broadband absorption in there without losing an real usable floorspace.
