Home Studio Acoustic Treatment

[pabloq]

Hi,

I’m planning to treat acoustically a room in my home for recording and mixing rock music. The room has enough isolation so I only want to treat it acoustically.

Room specifications

The location of the room is in the backyard and is quiet enough.

The dimensions of the room are:
Length: 172” (14.33 feet)
Width: 135” (11.25 feet)
Height: 91” (7.58 feet)

Two walls are made of brick and the other two and the ceiling of concrete. On the left wall there are two windows an one door. The windows have double crystal.


Acoustic treatment

Absorbers:
3 bass traps (4” Owens Corning 703) for corners,
6 panels (2” Owens Corning 703) for walls,
2 curtains for windows.

Diffusers: a bookshelf at the rear wall.


I made a plan at scale in SketchUp.


My questions

Are good the number and the location of the panels?
Is it good the thickness of the bass traps and the panels?
What material the curtains can be of?

Sorry for my English

Hi, Welcome!

And, be sure, after 718 posts, my english still crappy too...

I covered (rockwool 4") the L/R front and rear wall/ceiling corners last year.My room is a bit smaller than your.Bass decay ("waterfalls") was improved A LOT with this treatment,but I yet had some nasty peaks on the 2º harmonic (around 125hz).

Then (my suggestion)...I started to treat ceiling reflection point and wall/ceiling front corner with clouds...basically the area on the ceiling above the monitors and my head.And I had a great improvement on peaks and stereo image.

I have two 2' X 4' clouds, one 5" and other 8".

I´m just a musician that mixes sometimes...you will obviously have better advices here from guys that really are pro in acoustics, but there´s my "humble" experience.
And dont forget the measurements (I do with the Room Eq Wizard).

I'm just a rookie when it comes to room treatment, but I have read several places that the ideal listening position is 38 percent of the distance into the room - that is, your ears should be 38 percent into the longer length of the room, rather than right up against the wall.

Have you been to Ethan Winer's site? www.realtraps.com -- it has lots of useful info.

Both good answers so far. Seating position is very important. Correct on the sizing for bass control.

My general thoughts are you're on the right track - just not enough bass control. Also, the bookshelf will do diddly for diffusion - that's a myth. In that room, you're not really far enough away to make REAL diffusion effective. IMO, you'd be better off with a couple 6" thick panels with a light reflective facing on them (like FRK/FSK) to kill any bass nulls off the rear wall.

Thanks for your replies

I'd be interested in knowing how this turns out. I have a similar room size and door placement and am getting ready to undertake the same project.

To respond to your question about curtains, something heavy and with a lot of folds. Velour is a common one, but anything that is really thick should work. Other than that, the others have covered most everythign else pretty well.
