Acoustic treatment help!

[nomadx]

I have a little treatment at the early reflection points, but I need opinions on where to put bass traps and/or additional treatment. Thanks for your help. I've attached the layout of the room. It's not optimal as a mixing room, but it's what I've got.

If it's at all possible, I'd switch the "home theatre" area with the "mixing" area. Where you have the mixing area now looks a lot narrower than the home theatre area.

Thanks, Rami. I wish that were possible. The entertainment center is huge.


I don't think I asked the question very well. I realize corner bass traps are needed, but I'm not sure if I would benefit from every corner having one in this room. Anyone?

I just had a thought for a DIY bass trap design; anyone ever used sheets of steel mesh as a frame for fiberglass or rock wool? I'd rather not get into the woodwork for this.

Ah, yeah that's what I thought. That theatre desk looks pretty wide.

You can never have enough bass traps, really. I think it would take lots and lots of bass traps in any room before one would come close to reaching the point of diminishing returns. Don't forget the floor/wall and ceiling/wall corners, too. Not saying you HAVE to cover them, but as long as there's an exposed corner, there's room for a bass trap.

I would bass trap the front corners heavily (with something like Superchunks/TriTraps or Soffit Traps). The home theater corners likely won't give too much of a noticed effect in the studio (but, you could always treat the home theater space too!!)

Considering you don't have much corner space by you, I would probably additionally trap the wall/ceiling corners around the mix position (along with the first reflection points).

Since you don't have too much space for tons of traps - make them all thick as possible so they're all able to absorb any resonances. Luckily, with the odd room shape, you shouldn't have as intense of problems in the bass as some small square rooms.

Thanks a lot guys. I'm looking for superchunk DIY ideas now. I also have to find a place to order some roxul, which seems to be a bit cheaper than the 703. No one in my area keeps that stuff in stock. a

That stuff wouldn't be ideal at all. Not rigid enough. I use it quite often for tile underlayment.

If you don't wish to use wood, there is this build option. I made 10 of these. Actually quite sturdy, lightweight and portable. You can see that I hang two of them @ my website, in my control room when I record vocals.

Oh yeah, do not use the batting! It looks like crap and just adds to the expense. There is no need for it.

Where do you live? SPI is a great place to find Roxul 80 in the states.

Thanks, jimmsy69. Nashville, TN is the closest location and that's about 3 hrs away. My local Lowes and Home Depot can order it for me. You mention the Roxul 80 2" boards. Should I use the safe n sound 3" or Roxul 80 2" for the superchunk, triangle corner traps. It looks like the 2 inch will give the size triangle I see recommended. The boards for the safe n sound are a tiny bit smaller. I guess that small difference in size makes a big difference in sound.

Attached is my proposed layout. I'm thinking superchunks in corners 1-4 (possibly 5 and 6) and wall traps in the designated wall areas. Would this be a decent plan of action? Will the half-height corners benefit me much? Also, should the wall traps be 2 or 3 inch thick?

I'm also thinking about moving my mix desk away from the wall a foot or two; would that help?
