Walk around the room doing single loudish claps, clicks with your mouth and higher pitched "oh" sounds. Go to various places in the room, facing different direction for each place and listen where you get a nasty reflection or secondary sound. Then get a chair move it around to similar spots and do the same. My guess is that around the middle of the room, facing the window at seat height will be least harsh and most neutral.
Please let me know what happens and then I can help further..... |
Sorry I'm a day late! Was very busy yesterday and totally forgot :(
Anyway, I tend to get secondary noise coming from in and around the corners of each wall. These slightly lessen when I'm on a chair. In the middle of the room facing away from the window, I think I can hear a very, very slight reflection, but I also get the same when facing the window. Although I think your right, facing the window seems to be the best place. I personally would've preferred facing the wall away from the window, as I'm on a main road and facing the opposite way might rid some noise...Anyway, I will leave it up to you :p
Hope this helps! |

Good, that's what I was hoping for. Don't worry about facing the window too much. Get some good thick curtains and that will very much reduce the external noise. I also think that the disadvantage of noise from the street, is outweighed by the disadvantage of having those secondary reflections pointed at the back of your head if you face the wall. So it's the lesser of the evils, and much easier to treat against.
The next stage will be to set up your equipment against the window wall, moving the bed to the wall with the wardrobe.
THE MOST IMPORTANT FACTOR IS YOUR LISTENING POSITION - everyhting else is just secondary and is treated as such to support the this position. I don't know know how much you know about speaker placement but I'll start from scratch:
You want to be setup so the speakers and you form an equilateral triangle, like so: (CLICK ON LINK)
http://files.dahnielson.com/2008/03...acement_top.png
The speakers nee to be at head height so when you turn your head to face each one, it is flat "looking at you" and not pointed up or down. If you have them on stands, great - if not you need to decouple them from the table, as this affects frequency response and correct reproduction of sound. The easiest way to decouple them is with auralex speakerdudes. They can be picked up only $40 and make a massive difference to monitoring quality
I am assuming you have at least semi decent/entry level monitors (not just hifi or PC speakers etc.) - if you don't the don't bother with the speaker dudes.
After you have your kit setup, then comes room treatment and this can be guessed just by looking at the room, but is better done when when your kit is set up so you can test placement of tiles or rugs (on walls) etc. My guess is that you'll need to hang something directly behind you, on the door wall, probably a large rug would do it or large-ish general (broad frequency) acoustic tiles.
You actually don't have to worry about that much with this room now - the floor will be fine, the curtains will sort out the window, then a small treatment issue with the wall behind you and the rest is just minor adjustments for any problem spots. |

Great advice, definitely the best I've been given. Thanks a million man, I really do appreciate it! At the moment I'm still saving for some things, I'll be getting a pair of HS 80m's, so I'll look into those speakerdudes :) I'll let you know how things go, could be a while though.
Thanks for taking the time to help out :p |

No worries! The HS80's are great and the speakerdudes will be a good compliment to them. Just PM me or bring this thread back to life when you're ready.....good luck!!! |

Hi Rann,
Was wondering if you could give me some advice for my room, ive included all i think you need, i need some advise on placement of desk and speakers. also on what acoustic treatment will work best and where to put it.
1. What are you using the room for? Composing & mixing, the room untreated is causing mixing issues.
2, What are the materials of the room? Brick and plaster and also plasterboard and plaster.
3, What is the floor? Carpet
4, What is the ceiling? Flat plasterboard and plaster.
5, what furniture or other items will be in there? Just studio equipment.
6, is it a basement, ground floor, or upper floor? 1st floor
7, Are there many windows? 1 window
I will get the measurements of the room for you and draw you a small plan so you can get more idea.
this is where i was looking to get my acoustic foam from and also some bass traps, would you mind having a look for me and seeing what types are suitable for the room.

Many thanks if you can give some of your knowledge and time. |

| How do upload a pic of my room plan? i drew it in word how do i get it as a pic on my reply? |

Hey Mark, no problem - need a bit more info though.
images/photos can be uploaded to file servers such as imageshack or photobucket, then just insert the link using the IMG button when you post the reply.
As for a flooplan, that would be very useful but some photos of the walls an one of the ceiling would help too.
If you're just composing and mixing it makes it a fair bit easier - you will be mainly treating the room so that you can hear the sound more accurately. This will obviously effect everything from your workflow to you comfort level to fatigue time. I just need to know some other details....
When you say you're having mixdown problems, what exactly are you having trouble with?
What speakers do you have? Again, What stands do you have?
Do you need to just treat the room for your benefit, or to soundproof your elderly neighbours from that "god awful techno music"? :D
As for that shop, doesn't seem too bad but not the cheapest and most of their stuff looks like Auralex knock offs - they very well might perform the same way but they're not cheaper so why risk it?
The auralex stuff has had a lot of R&D so I trust their stuff and have always had good results when using it. They also make a sensible range products, so picking out the nits needed is quite easy.
Check out:
STUDIO SPARES
They have a good range and their staff aren't bad - they'll try to bump you up on what you need but just keep firm and they like to do deals, so have a good haggle with em.....We'll get to that later as there's no point contacting them until you know what you need.
Let me know...... |

Hey been a while but wanted to research a few bits and not rush into things -
Mixdown issues are alot to do with high freq bouncing around i think. irt sounds hissy in the room but when i bounce it off and play anywhere else its fine. I just think i could hear alot more of my high frq mixing and get it better if i could dampen the sound of it in the room.
I got behringer truth monitors, but am looking atm into buying dynaudio bm5as. They just sit on the table in front atm, probs need some speaker dudes.
Dont need to soundproof thats fine - i do music in the day when knowones about.
ok hers my pics and plan - hard to take the pics as its so small room.
dimensions - 2m wide door end 160cm wide speaker end 2m 20 cm long
room plan - 
Heres a link for the rest of the photos - http://s563.photobucket.com/albums/ss77/markiliffe/
If you can help me out its greatly apriciated. |

You're not serious are you? Curtains won't absorb any significant noise coming from the outside. Road noise is mostly low frequencies anyways which the fabric will be useless against. Besides, absorption isn't the same as isolation.
I would try to seal the window somehow. Maybe thick MDF board fastened using screws, with weather stripping inbetween to get an airtight seal. Great sound isolation properties and very easy to remove later. |
