Hi.

Can someone tell me if the plan I have to treat my room is suitable?

I'd appreciate all advice.

I've attached some jpegs of what I think I'm going to do.

I'm going to use Rockwool RW3 1200x600x50mm - (60kg/m3).

I'm going to build 2 X 6" traps(4' X 2') panels and put them horizontally on the wall by my bed directly opposite the speakers.

Then put a 6" deep(4' X 2') traps either side of the speakers at an angle in the corner of each room near the window wall.

Then put a 4" deep(4' X 2') traps either side of the monitoring position at the point of first reflection.

Possibly a 6"(4' X 2') traps in the alcove corner.

And finally at the 3 ceiling corners I can use, I'm going to put a 6" (2' X 2') traps in each.

I think that will give me my best shot of achieving a balanced room, or at least as close as I can get.

What do you guys think about the plan?

And finally, do you think that leaving a space of say 2" between the wall and the traps will be better than having them directly against the wall?

I'd appreciate all advice, Ste.

ok...I'll give this my 2c...

A couple of things...
The dimensions of your room are throwing me.
125mm + 25mm + 125mm...doesn't that equal about 11 inches (ish)? Kind of a small room doncha think? :p

Basically, ya have a square room. Square rooms are gonna be a bit more of a bitch. 4 parallel walls n all. Ya gotta tame it a bit.

But...focus in on your bass traps like you're planning and start with the corners. If it were me, I'd just do superchunks in the 4 wall corners. Floor to ceiling.
They're simple to make (but a bit time consuming) and will make a nice impact on mixes and tracking.

What are you planning for the wall and window in front of your desk/monitors? A direct reflection is gonna skew your ears while you're tryin to mix.

Maybe consider a cloud above where your desk will be...?

Can you get your desk/monitors off the wall a skosh?
Any room for that?

Did ya bring beer?

:D
 
The window is going to be a REAL problem - lots of issues with a surface that big, smooth & behind your monitors.
 
So far chasing good room acoustics I've moved from a terrible position where I had my PC in the corner alcove. I was getting major boom in there, it was terrible. On another forum someone advised me to move the setup to the window position. It was a major improvement in terms of monitoring the sound and I finally figured out what a sweet spot was.

I assumed that having a 4' X '4 RW3 Rockwool bass slab behind me on the wall opposite the window that that would take care of any problems that the window might produce.

The guys I spoke to also said that I should get some heavy curtains that would fit behind each speaker.

I think I know what you mean by a cloud, something that hangs from the ceiling. I could look into that.

Thanks for getting back, really appreciate it.
 
I had a 4 pack here last night, each one measured 2mm diameter X 5mm tall. It was the only thing I could get through the tiny door. Made for guys in the far east I think. Called - Idrinkaya!

Feckin shinola night.

I've sent off on eBay for a new tape measure.

It's the only way to make sure of a good beverage.

Too true. And a good beverage is a must when ya need to make an ugly chick beautiful.
:D






So...uh....what are your room measurements?
:drunk:
 
Hey db.

I've had a guy today near where I live say to me that this is how I should treat my room which is approx 11' X 11' x 8.

I'm going to use Rockwool RW45(1200mm X 600mm X 100mm) X 8 slabs to treat my room.

1 in each front corner of the room 1200 X 600 X 100(can't do behind me in the corners as there's a door and a open closet).

A 1.2m squared panel behind my listening position where the monitors send a lot of their sound.

A 1.2m squared panel floating above my head angled 15 degrees.

And a 1200 X 600 X 100mm either side of my monitoring position at the point of first reflection.

Given the room, do you think this sounds like a decent plan?

And also as you might know, is it better to have the panels hanging off the the walls with a space between? I've heard conflicting rumors on this.

I'd appreciate your ideas, cheers.
 
"is it better to have the panels hanging off the the walls with a space between? I've heard conflicting rumors on this"

and actually, so have I. So I dunno.

And it does seem like a decent plan the dude gave ya. Just remember tho, in square rooms, you're bass traps (especially in corners) are gonna be your best friend. I'd do as many as I could fit. Really not much of a worry to overdo the trapping.

:drunk:
 
Thanks man.

I'm gonna go with what he said and then put more in if I can and need them at a later date. I'll do a bit more reading on the wall gap and see what I can figure out. Thanks for getting back, appreciate it. I'm off to find a decent sized can of beer. Chat soon Db!

100mm = 4" - this is not thick enough for a bass trap to tame the low frequencies (sub 100hz). your corner traps should be at least 6" and if you have those panels you might as well double them up and make them 8" if you are going to do panels and not superchunks.

Examine the charts and you will see the thickness required for the specific frequencies.

I just went through a lot of this, these threads might give you some ideas also:

Thanks for getting back arc.

The guy I talked to said that acoustic treatment was almost always overplayed and that what I mentioned before would be enough to bring the room under control to the point where I could mix effectively. As for what you've given me there, after a quick read, there are a lot of people who would suggest superchunks as a general rule.

I've had so many different people tell me so many different things now that I don't really know which was to go.

Time to get another beer methinks.
 
I'm not an acoustician, I just play one on TV..... ;)
but...

I had 4" thick traps straddling my corners when I first set up my room. It was ok and better than what I had before which was nothing. When I decided to try this superchunk idea, I placed the 4" elsewhere in my room and went floor to ceiling with the chunks in all 4 wall corners.

The very first tune I started to track (starting with drums) was clearly tighter and punchier and that was just monitoring thru my headphones. Hadn't even hit record yet. So it made a difference from tracking onward.
I'm not great at mixing yet but the fact I'm hearing a more realistic representation of what's really going on, I can make better decisions.

Not to dis yer pal but controlling the bass frequencies in your room IS important. And especially in a small square room.

my thoughts...:drunk:
 
Hi

Hey Db.

The guy wasn't a personal friend db, just a guy at a company that i phoned to see if I could get them to come round and do a survey of what my room is like and what I would need(I was then gonna do it DIY on the advice they gave).

He was pretty adamant though that I'd be able to do it as I'd said above. After reading around I think I might need to go with the superchunks, but the problem I have is that I have a door and an open closet behind me. This room is a nightmare.

I'm thinking of using 2 superchunks in the corners to the left and right of the monitoring position but not sure if that will be a good benefit overall 'cos the speaker cones aren't directly aimed at them.

I could do those but the other two can only have a 2' X 2' bass trap in the corner in the roof at best.

What do you think?

Also, I'm getting different reports for the material you should use, density wise that is. Which do you think is best:

Rockwool RWA45 1200x600x50mm (45kg/m3)

Rockwool RW3 1200x600x50mm (60kg/m3)

The price for buying works out near enough the same. I just want to know which is best for which app. Broadband absorber and superchunks? Or whatever the terminology is.

Doesn't matter if the cones aren't pointing at them. Bass frequencies go everywhere.

as far as the best material is concerned, ideally Owens Corning 703 rigid fibreglass is considered your best choice.
 
Hi rami.

Can't get hold of 703 in the UK so have to go with Rockwool.
 
Actually, from what I have learned from my own research, Roxul 80 performs a bit better than 703 below 150hz. The problem lies in the build. Rock wool is much less rigid, and needs to be supported in the framing. Roxul is about 1/3 less in cost in my area. Just bought another 12 panels worth of material to do a second round of absorbers. Going to combine two frame designs consisting of drywall corner bead, and pine back frames. A thread will be dedicated to this build.

Didn't mean to jack the thread. Just got some economical plans to share very soon. :)
