My bass traps are a little smaller than that (I cut the 1200 x 600 RW3 panels into 8 so 600mm across the front). I simply don't have the room to go bigger but yours should be better. Go floor to ceiling in as many corners as you can and consider a limp mass membrane in front (hung in the frame for the fabric?). You can't have enough bass trapping in a small room and your resonances will be an octave lower than mine so will need bigger traps.

How do you plan to treat the ceiling, leave it as is or plasterboard it? If the latter I'd also suggest ceiling clouds over all the recording areas*, flutter echos are horrible and carpet won't do much (well, nowt actually) to tame them so the ceiling needs treating.

* Actually I'd stick a cloud up there even if you leave as is to make things a bit more predictable.

Disclaimer, like Drew I'm not an acoustician but, also like Drew, I have treated my own room/studio in the last couple of years and have been happy and impressed by the results a small budget can achieve.

Wthe the exposed joists I eek out a bit more height. I am considering painting it white(ish) to give a brighter overall feel to the otherwise dark room.

I have a few ideas for the ceiling.

1. Fill the spaces in the joists half of the joist depth over the drum kit and mix position.(6 in or 15.5 cm)

2. Suspend panels I have already built above in these areas.

Has anyone ever seen the spaces between joists used as random diffusion?

Thank you

It did cross my mind that, with limited height, putting absorbers into the spaces would make sense though I'd cover at least ⅓rd of the ceiling area...

Never seen that done with diffusion but for diffusion to work well it needs to not be large areas but lots of small surfaces at different levels. I've seen curved or wavy panels but google 'acoustic diffuser' in images to see the usual stuff.

I think I will fill the joists all along the perimeter for bass in those dihedral corners.

Then over the drums and mix station.

Any other spots that would be good to hit?

Obviously mirror points but then anything directly above a possible microphone position. Otherwise if you cover about ⅓rd of the wall and floor area* you should hear a huge improvement in room sound.

* Gut feeling suggests you should space the panels, apart from the wall mirror points, so they are directly opposite a gap in the panels on the opposite wall but I don't know if that has any basis in acoustics.

GIK recommend doing exactly that, if I remember rightly.

Build like a Pro has been a good read so far. A good bit of the info there is beyond what I am going to do here in the short term.

10 years from now it might prove an even better asset.

Tha k you again for suggesting it.

Yep, there's stuff there that's beyond what I needed too, but once you understand the full concepts you can then make informed decisions about partial solutions. :thumbup:

Ignore the post count, I have no idea what I'm doing...
