Thankfully we've reached the end of that phase (I hope anyway). That's not to say the status quo is not up for review from time to time mind you.......

A serious question for a second -
Drew - are you basing the sizes and numbers of absorbers on the size and shape of the room? Is there customized math/science behind your constructions? (Not being cheeky here)
I ask because I built some based on guesswork, size of absorbing materials available and trial and error. They work but if you found a place on the internet that wouldn’t make my head spin with math calcs I would like to see it.

I doubt it. Anything that works for a 'rectangular prism' (i.e. a basic room shape) starts to fall apart once you move equipment and furniture into it as the surfaces become far too complex to model mathematically.

Plus I think that the maths starts to fall down for the size of rooms that we're considering here.

There's no science involved, just some 'best practice'. Bass traps in the corners (you can never have too much bass trapping), broadband absorbers at mirror points spaced off the wall, bit of diffusion on the back wall.

And, if you've got a big expanse of wall or ceiling still exposed after you've done that bung an extra panel up in the middle of it. :thumbup:

I've heard said that a useful rule of thumb is to have 30% absorbers, 30% diffusers and the remainder left as is.

I'd certainly agree with the notion of no more than 30% of the wall area covered in absorber panels. If you go higher than that the room can become overly dead/dull, particularly in the mid and high frequency regions, with the result that the space sounds boxy and coloured.

I'm not entirely convinced about diffusion in a small room. It's a good idea in a larger space, for sure, but in a small room I've found it can be difficult to give the diffuser panels enough space to actually diffuse the sound properly. If the panels are too close to the listening position they can create a phasey sound, which isn't helpful!

But the approach I'd recommend is to set up the absorbers and traps first -- corners, mirror points etc -- and then have a listen. If it becomes apparent that some diffusion is required, it's easy to experiment to see where to place them.

That is what I have done, no diffusion simply for space reasons, and I'm happy with the result.

My diffusion will largely be by the default option of having a bookcase there. :)

Mine is by having the room so full of 5h1t that there isn't a flat surface visible anywhere.

I think that's true for most of us, Sam! :lol:

I moved stuff around recently and, to make space, a couple of guitars are now hung on the wall. One of them is a brass bodied tri-cone resonator and the problem is that - it resonates. I haven't tried to do any serious mixing since the move but if you raise your voice you can hear it ring out. I'll probably have to ask it to leave the room at certain times :headbang:

A little bit of Christmas stuffing perhaps?

It just goes to prove that I really, really, need a dedicated guitar room (in addition to a live space, a control room, a mic store etc, etc)
