Live room rescue!

audio hobbit · Post by **audio hobbit** » Sat Sep 06, 2003 5:00 am

Ok, I am going to attempt to post a drawing of the live room at the studi oI am doing alot of work out of.. I really need to get some ideas so that I can present them to the owner and hopefulle make this space useful.. it currently has a boatload of 2" auralex on one wall, and sounds horrible, mr flutter echo lives here and the entire room seems way hot in the mids.. really ugly. here goes, sorry for the drawings!

The sliding glass doors go into smaller iso booths that are about 9 x 6 with a sloping 7' - 5.5' cieling, they are dead rooms and are ok for now so i left them off the drawing, They may or may not go for replacing the doors, my thought is that they will not..

here is the side profile, the cieling height is approx 14', and the sides are 8" up to the soffit, the flat part of the ceiling is 6 ft wide... in the first picture, the top wall is 21'6", the west wall is 19', and the bottom wall is 23'6 to the insidle of that little alcove in the corner.

This is a nice space. It certainly looks like it has potential.

How much are they willing to spend? Is sound isolation a big consideration, or is the room pretty good as far as that goes?

I am not sure of the budget.. as usual! Isolation is not so big an issue, we are free standing, back in the woods so to speak, and the CR to live room iso is pretty good. One thing I had thought abotu was dumping the sliders that lead into the iso booths eventually, maybe this will provide a good excuse

I would keep the iso booth doors the way they are. Most importantly you want to break up those parallel walls. Diffusion would also be helpful. This room would be an excellent candidate for John's and my Diffusive Slot Resonator design!:D http://johnlsayers.com/phpBB2/viewtopic ... 3&start=15

I would modify the room similar to the layout below. Angled internal walls could be covered with diffusive mid band absorbers. The grey areas behind the walls are filled with acoustic hangers. http://www.saecollege.de/reference_mate ... encies.htm Openings to these rear volumes should be positioned at the floor and ceiling intersections.

interesting.. looks cool..

Couple of questions:

1.how much depth from the existing wall for hangars?

2. Any treatment for the ceiling?

3. speaking of the ceiling, should the diffusion/absorbition fillow the angle of the ceiling as high as possible, or just up to a certian hieght? ( I assume all the way up? )

Thanks for all your help with this, I know everyone is swamped with work and getting the site moved, I really appreciate your time!

I drew it approximately to scale, so the deepest wall "peak" would take about 4 ft from the room (from the face of the diffuser/absorber back).

The hangers would fill whatever space is left behind the absorbers.

Yes, the new wall sections would extend all the way up until they intersect the ceilings.

I calculate that you loose about 10% of the floor space. Not a bad tradeoff for a now "useful" room.

Ok.. my user name went bye bye for some odd reason, so audio hobbit is now fathed, sorry for the confusion....

How should I treat the flat aera of the ceiling? Also, what type of insulation do i need for thehangars? 703? and how rigid does the board it is glued to need to be? I could not figure that out from the SAE page...

Thanks again!

bump.. sorry for the bumps..

I would probably put DRSs on the flat part of the ceiling as well. Oh, and did I mention that all the auralex should be removed as well?

This is a live room and a nice, smooth, lively reverberant field is desirable. First modify the room to ameliorate the modal, interference, and flutter issues. Then listen to a variety of instruments, ensembles, and vocals in the room. If the room is still too bright, then you can start... sparingly... hanging high frequency absorption on the walls to warm things up.

Acoustically, I like the idea of using a dense flexible material like linoleum for the hanger panels. I also like the idea of attaching the insulation to the panel only at the very top. This way the panel and insulation can rub against one another and dissipate more energy through friction. 703 is a good choice. John or Steve might have different ideas about building hangers.

Not really - that sounds like a reasonable idea - I've always used fibreboard but - linoleum sounds cool to me.

cheers

Hi there, me again, sorry for dragging this thread back from the abyss, but I have been moving house and making records.. not having an internet connection at home is a killer!

I am curious as to weather or not I can do a "wall" of 703 behind the slats as opposed to hangars to save on construction costs? I dont want to shoot myself in the foot, just looking for alternatives.
