Hi everybody,
new to the forums looking for some advice on treating a room (I know virtually impossible to get completely under control lol)
Basically I have a small square room that already has some treatment (generic foam wedge style) I was wondering what my best options would be regarding treating the room! One wall is brick where I have the monitors which are facing a plasterboard wall. Would I be better putting the monitors near the plasterboard wall facing the brick or leave them where they are? And what density rockwool would best for building my own bass traps?
Look forward to your help
Aka Speedy

I put everything I know in a book.
hexspa.com/listening-room-ebook
It's free and only 28 pages with half of them being pics.
But to directly answer, apply the standard principles.
Cheers,

I was wondering what my best options would be regarding treating the room! This short article (which is also linked in the READ THIS FIRST "sticky" post) gives a good overview: Acoustic BasicsThen feel free to ask questions here specific to your own room.

Typed in the link and it goes to a buy this domain name website.... Copy paste? The link works. But of course, reading the stickies is always recommended.

Hi so I've read up on the acoustics and I've built 6 bass traps using rw3 60kg density rock wool 1200x600x100m with a 4 inch air gap. As the room is so small I can't straddle the the corners. I have a door in one corner and as the room is coming out of the house on a sloped roof part of one corner is an angle that I cannot get a bass trap into. Also the wall behind the listening position is very close to me! Would I need to fully treat that wall with the traps or put in as many corners as I can physically get them in??

You can also place the panels parallel to the wall including an air gap.

Yes, since the wall is very close, it's a good idea to treat the entire wall AND as many corners as possible. And in the corners you can't straddle, as Hexspa says, you can place traps parallel on one or both of the walls in the corner with a 4" space if there is room. I'm sure Ethan has an illustration of this alternate bass trap positioning in the "Sticky". I don't think you ever told us your room dimensions. Either that and or a drawing is always helpful so we can see what you're dealing with. Cheers, Rock

Cool beans. Currently working away on a '16 nights in a row shift' to build up some duckets for chrimbo so not able to get room dimensions until closer to Christmas but it's a small cube just over 8ft each direction. I'll probably just post pics rather draw as that's not my strong point 😜

Realistically you would make larger gains appropriating a bigger room.

I do have one in the next room but because of building work going on it's jam packed with all sorts of crud! It's rectangular as well. In the mean time though I want to treat my current room as much as possible! At least then I'll have all the treatment sorted for when I move into the bigger room!

Cool.
Ethan has 40 traps in his room (about 1700ft3 iirc).
I have 20 plus super chunked corners in roughly 2500ft3.
His room probably functions better acoustically.
(Probably more comfy too considering I have no couch.)
You can use that info to get a ballpark of how many panels you might need.

So I'd be looking at roughly 12 bass traps for a room around 8 ft square based of Ethan's numbers....would diffusion in a room this small be pointless?

If you're assuming the room volume and bass trap area is proportional, yeah, 12 is the number but I'm not sure it works that way. With such a small cubical room, you'll probably need more bass traps; the four vertical corners are 8, you still have 8 corners left so at least cover the ceiling/wall corners and any floor/wall corners that you can (I know the floor/wall corners take up floor space so in a small room, you might only fit a couple in). Instead of diffusors, it's better if the back wall be completely absorbent.
Did you ever consider acoustic measurement with REW? It won't change anything but it will show you the improvements your treatment is giving you.
Cheers, Rock
