Evening all,

I'm soon to have a small room in a typical semi which I'm going to be able to use for music. Predominantly this will mean mixing/listening, but now and again the odd vocal/acoustic recording. The room isn't very big at 10lx11wx8h, so I'm thinking quite a lot of treatment.

I don't have any soundproofing concerns.

Rather than building individual traps out the standard rockwool/cloth combo, I wondered about building a frame over three walls (fourth is a window) and ceiling, spaced with a 4" air gap and lined with 4" rockwool.

Since I don't want any kind natural recording acoustic out of the room, I'm not too concerned with making the room 'too dead', but could this approach have any other problems? Would the standard RW3 have reasonable flutter echo reducing properties in this kind of configuration or would I need to use standard 'foam' too (which I have some of).

Would I get more of a benefit from simply treating all (front two vertical corners, front three ceiling/walls and floors...) the corner interfaces with mini-super chunks?

Thoughts appreciated,

Rod

I am guessing this is in feet? If so then

You definitely not have much room sound left in the room, but it seems like a bit over kill and would take up a lot of room that you really do not have. I myself would not think you have to go that far. Take a listen to this video and you will see that not all the walls are covered and the quality (music that starts around 3:30 and the tests results) are pretty outstanding. Note there are english subtitles.

Not sure you would get more "benefit" but would think it would do the job if all the corners are covered. If you want to go one step further then maybe think of about a soffit design. Basically it is 17" square that goes in all wall to wall corners and ceiling to wall corners. Kind of like this (sorry posted before....)

Hi Glenn,

Thanks very much for your response - I was a bit worried that I might have to completely overrun the room with material to tame the lively acoustic.

The video really demonstrates a big change in acoustic, how much importance would you place on the diffusors?

Thanks again,

Rod

For your room? Way down at the bottom of the list. I would get the low end tamed with early reflection points then use diffusion for flutter. Honestly though in a room your size (depending on budget) absorption for the flutter will work just fine.

My room is even smaller and virtually a cube! 2.3x 2.6 x2.6 mtrs (8x8.5x.8.5feet near as) and I had vitually given up on making it reasonable for voice and acoustic guitar recording but a chance find of some foam sheets, 1x0.5mtr x25mm £15 for 2 at B&Q gave me hope.
I had already nade up two 750x750x70mm panels filled with a kapoc material but these seemed to do little. However, I suspended one in front of the now DGZD window (1.3x1,3 mtrs) and fitted one across a corner "at which" a monitor fires.
The foam was mounted on 3mm hardboard and "velcro'ed" to a wall to the left of one monitor and back of a door right of the other. The door panel can also be lifted off to hang on chains which suspend from the ceiling and put the panel behind the mic (window at us back). The rest of the foam fills the wall space between the monitors.
Son reports a definite cleanup of the sound even using our most "difficult" mic the big Sontronics ST-C2.I too think the bottom boom has been tamed but being clinically deef I am no judge!
And 50% of the floor area is now 3mm hardboard, shiny side up. I have no need of diffusers, the room is stuffed with electronica and shelves of CDs etc!

Hi Dave,

If a room of that size can be improved then I'm sure I'll have no excuse! Thanks for the reply,

Rod

Take a moment and watch (also listen ) to this video. It has some testing for the first 3:30 minutes but then has some record music with and without treatment.
