Title: I may possibly have the worst room of all time.
Post by: trock on December 17, 2006, 09:00:16 AM
Hi

first time post in this part of REP. i am just a home hobbyst who has neglected his actual room up until now. i have spent money on everything else and now realize its time to address this part of my setup if i am going to get any better in terms of sound quality.

ok so what is this room made of??

why

1) carpet on the floor
2) 8 windows with no covering
3) drywall on 3 walls (the ones with the windows)
4) 1 hardwood wall, with french doors with 30 small windows combined
5) and 1 hardwood ceiling

i probably need to post some pics to make sense of this. the room itself is around 12x18 i would say

so is there any hope for me? and should i post some pics??

i would say that my mixes actually translate pretty well to my car or home stereo once i am done but its much more when i record an acoustic guitar/mic'd that i am having some issues. more than anything i just wondered what could possibly be done to a room like this.

if anyone is intereted i will post some pics and you can have at it

thanks

tim

Tim,

> the room itself is around 12x18 i would say ... so is there any hope for me? <

Of course there's hope. Windows are not a big deal. They reflect a little more at very high frequencies compared to sheet rock. The larger problem in most rooms is the severely skewed bass response and excess ringing.

Until Fran shows up with his expert advice, start here:

just kidding.. Ethan is right, we have to start with some bass trapping (as always)... then control some of the first reflection issues,....

It's all been discussed here a few times, but of course we don't mind going over it a few more!!

HAHA

thanks! i have been doing some digging since my first post. i will try and post a couple of pics tonight when i am at home. hopefully that will help out

i am glad to hear that windows might not be as bad as i thought since that is what makes up most of this room. it used to be a sun room and was the only room i was allowed to take over Smile

anyway i will post some pics tonight and see what you guys think.

thanks!!

Excessive windows can actually help (and hurt).  They help because they aren't structurally significant enough to "retain" much low-frequency sound, which means your room's bass response likely won't be as "lumpy" as it would otherwise be if the windows were as rigid as the average wall.  On the other hand, windows hurt, because they make the room more difficult to analyze.

See, there's no free lunch!

i did just realize that alot of times i will mix a song an it is bass heavy and muddy when i listen in the car. i come back and i roll off the bass on instruments and lower the bass itself and then i am usually pretty close. anyway here are some pics

thanks for the help

in the last pic you can sort of see the left wall is literally stained wood the whole way down with a set of french doors in the middle

ugh

well there you have it.

again thanks for any suggestions. i did start reading all the articels here and suggestions so far

Tim,

> again thanks for any suggestions. <

You have too much gear! Twisted Evil

Seriously, you'll find most of the answers here and in my FAQ. But here's the short version. All rooms like this need:

* Broadband (not tuned) bass traps straddling as many corners as you can manage, including the wall-ceiling corners.

* Mid/high frequency absorption at the first reflection points on the side walls and ceiling.

* Some additional amount of mid/high absorption and/or diffusion on any large areas of bare parallel surfaces, such as opposing walls or the ceiling if the floor is reflective.

Woot, I'm not alone!   Rolling Eyes

I'm in a similar place in our house... the sun room, which was originally an enclosed porch _outside_ the house.   So I have windows on three sides, and the brick wall of the house on the other.  The room is about 25ft long by 14 feet wide, with the brick wall on the long dimension, and 8 ft ceilings.

What I've found to work surprisingly well is a to cover the windows on the long wall with rigid fiberglass panels, and leave the two short walls/windows and the brick wall uncovered.  It's symmetric, at least, and on the dead side but not lifeless.  Works for me, but I know I'm breaking a lot of rules here... mixing with a dead wall behind me, setting up my mixing desk along the long wall rather than a short wall, etc...

I am tempted to stay out of this one... but you know I can't resist...

Ethans right with the basic steps.. Broadband Bass Trapping in the corners, First Reflection Control.. these are the first issues that must be dealt with...

Yes, you will have to cover a window or two (or five??).. or else you won't address the first refections from side and front walls. You could consider some HEAVY drapery.. it's better than nothing!! But Ideally I would want to see at least 4-6" of Rigid Fiberglass as first reflection control..

You can't hide from mallick!! I have room in my house set up in a similar fashion for my skin flute.
