I need help for a studio bedroom!

[midiman123]

Hi everybody!

This is my first post on this forum, and I would like to say that this is a perfect forum for people like myself who knows some about music, but not so much about room acoustics!

I write music for Radio & Tv, and have a home studio in my bedroom, but I´m not satisfied with the sound in there.

From the concrete walls and ceiling, I get a "cold" and nasty sound in higher freq. in vocals and acoustic guitars.
(It´s pretty high up to the ceiling..)

I have tried these calculators, but I´m not really good at it
(I have some furnitures in my room that makes it hard for me to figure out what I need.)

I have bought new small speakers(A.D.A.M P-11) so that I don´t get to much bass in the room, but I suspect if iI treat the ceiling, and walls with high to mid freq. absorbers, I might need some bass traps anyway?
(I have a big bed in the room, does this dampen the bass?)

What Should I buy/or build)?
And where should I put it?

If anyone can help me with this, I would be even more happy then I am now..

Dear midiman,

I don't know about others, but I could not see your attachment. I assume it has the all important layout and room dimensions???

Also, the website for your loudspeakers claims a frequency response for the P11s down to 48 Hz. This will likely mean bass traps/broadband control for your room. I got this information from:

Hi Jeff & Thomas!
(Thanks for answering)

OooopS!

-Don´t know what happened to the file there!!
(I tried to keep it at 100Kb, but it was BIG anyway!)
I have mailed it to Thomas, so hopefully it should be up soon.....

Kind regards
Kenneth!

I've fixed it

Try this midiman for starters.

But could you explain it a little bit more?

- I thought it was a bad thing to have the speakers in the corners, and also in your suggestion, the rear of one of the speakers are facing the window.
Is that any good?

The sound of the right speaker will bounce further away(in to the end of the bed), while the distance for the sound of the left speaker will be shorter.
(Maybe you mean I should place the speakers so that they both are facing the back of the room?)

- And the way the desk is now, wouldn´t it generate a lot of uncontrolled bass behind the speakers?

I'm assuming you have curtains over your windows - the corner is a good place to put a bass trap.

Well, that window is the only one that will let daylight in....
But you say I have to "sacrifise" that for a perfect sound?

What kind of foam, treatment would you put in the room?

And If I put some treatment on the ceiling, how far from the ceiling should it hang?(It´s high up)

Thanx

What about this then:

Look at numbers on drawing:

1: Pyramide foam on pegboard up in the ceiling, slightly angeled.
(But how deep down from ceiling?)

2. Build/Buy 2 Basstraps, one behind desk, and one in the back of the room(covered with pyramide foam?)

3. I have already built a 3 frame on wheels(150x170cm) that I plan to cover with Pyramide foam, so that I can move it around and use it for vokal booth. Maybe when mixing, I can put it like this on the drawing?

4. Cover some walls with strategically placed 4" pyramide foam.

Is this making any sense at all?

(By the way, the wardrobe´s is made from a thin, spraypainted reflective wood material(Peg board?). should I cover it?)

-And, Is it ok to spray paint acoustic foam?

Anyone has a comment for my last outline of my room?
Please?

KK,

What about this then:
1: Pyramide foam on pegboard up in the ceiling, slightly angeled.
(But how deep down from ceiling?)

Minimum spacing from the ceiling should be about 1". Maximum would be about 6". Angling should be such that the "front" edge of the panel (closest to the corner) is the lowest (biggest gap from the ceiling) and the "back" edge (furthest from corner) is closest to the ceiling.

2. Build/Buy 2 Basstraps, one behind desk, and one in the back of the room(covered with pyramide foam?)

Assuming you just want passive traps, those should work well. Though, you can always use more if you find extra space in the room.

3. I have already built a 3 frame on wheels(150x170cm) that I plan to cover with Pyramide foam, so that I can move it around and use it for vokal booth. Maybe when mixing, I can put it like this on the drawing?

Mobile treatment is never a bad thing. You will probably find good spots and not so good spots for such a device.

4. Cover some walls with strategically placed 4" pyramide foam.

OK. But don't go overboard. As I've said before: "Foam doesn't kill rooms; people kill rooms."

(By the way, the wardrobe´s is made from a thin, spraypainted reflective wood material(Peg board?). should I cover it?)

It can't hurt. But I wouldn't worry about covering all of it. Just the parts that might reflect sound back to the mix position. Also, you might be able to position your "gobo" just right so that you don't have to cover it at all.

-And, Is it ok to spray paint acoustic foam?

Most definitely not. Paint of any sort fills the pores of absorbers, reducing its acoustical effectiveness dramatically. Even painting absorbers that claim they can be painted is not a good idea.

Thank you Mr Szymanski!
You answered all of my questions!

Cheers

(Ps. What If I need to "tune" a basstrap. Will there be any conflict to have a passive and a tuned opposite one another, or if both is tuned?)
