I want to treat my room a little bit, some ideas

[AntonioPetrole]

Before i am hit with a link, i just wanna say i have read about acoustic treatment and I have a decent understanding of bass traps, diffusors, standing waves, reflections etc. Here is a quick design i made (i know im amazing at drawing on a comp)

I have bass traps i am making and i am gonna have them on each side of my mixing desk going across the corners. I am also gonna have one above my desk between my desk and chair. Any other things i should do to treat my room? I dont have a whole lot of money ATM cause im saving a for a 5150 so anything within a decent price range ($200). My father is a carpenter BTW so anything DIY would be nice too.

Note: My floor is carpet and the door to my room is to the left of the closet.

Thanks in advance

I think you've forgotten first reflection points, which should be covered with a 4 inch rockwool panel, OC703 or similar. Cover them in fabric and put em in a wood frame and you're done. I'd also try and cover the reflection points at the rear of the room.

Also, in my experience, just 2 pieces of rockwool each side of the room isn't really enough to affect the bass in the room that much. I'd suggest building superchunk corner bass traps instead, or making sure the gap behind is stuffed like hell with rockwool. Seriously, the more the better.

Agreed, superchunk the corners or at least add a thick pannel across the floor-wall corner under the window where it won't take up your walking space. Treating any corner will help, so take advantage of that corner not being used anyway. Since it can just lay on the floor, leaning against the wall you won't have to worry about it being permanent either.

You might consider a 2 inch thick cloud made from OC703 above the mix position area instead of a bass trap, depending on the height of your room. The cloud could extend past each speaker on the sides and back behind the listening position, basically covering most of the ceiling above you and the speakers in that end of the room. Leave a 2 inch gap between the ceiling and the cloud.

2' by 4' panels built of 2x4's and some covering material with any kind of insulation fixed inside it of dense foam, or sound proofing board doubled up, and as said, 2 inches of the wall is going to help. I have researched DIY and there are many resources on the internet. Some sell expensive rigid fiberglass that can be built in the manner as said above with tremendous effect or premade, relatively cheap ( maybe $80-100 ) panels that are attractive. Google it mayhaps

you guys are tits (and i mean the good kind too!) I will revise this and post again. Thanks for all the help!

any kind of insulation fixed inside it of dense foam

I wouldn't say any kind of insulation inside, it has to be fairly rigid and the right density (between 30kg/m3 and about 45 kg/m3 or more if it's a bass trap). Even open cell foam has very poor absorbtion characteristics compared to OC703 and RW45 etc.

I've even seen absorbers made out of old shredded bits of denim compressed into a panel.

what about diffusors?

 

[Joematthews]

It's too small a room for diffusors to be effective, I think there has to be about 15 feet between the listening position and diffusor for it to really work, because the brain can't really tell the difference between the direct and diffused signals properly.

What kind of floor is in the room?

carpet

Depending on how much trapping you have the room might become a bit dull in that case, but if you can buy enough treatment to make it dull then you've probably got enough money to lay down a wood floor as well, so it's not really a worry, and as you're on a budget I think you'll be fine with reflection points, a cloud and heavy bass trapping. Update us with pictures and stuff when you get down to doing it

Also, try to move your listening/mixing position away from the wall, read up on the 38% "rule". This would be about 5-6' off the front wall. It's not readily apparent on the picture how far you're located...
You might have to adjust speaker position as well to keep them in the sweet spot (about 5' [from the listener] for near-fields??? correct me if I'm off here, but this is what I've read and use myself).

But then we get into to SBIR.. and more trapping.. grumble grumble.. damn acoustics..

Go on the Genelec site and read the magazine articles. Very informative although rather repetitive.

Thats what I've done:

In my case, that was the best decision, imo.

I imagine a fairly dead room is still preferable to an untreated one anyway

Oh hell yeah
