In reference to the recent discussion of acoustics and room treatment, I took a more detailed set of pictures that detail the size and type of room…

A bit more insight and audio here as well…

If you've got any other suggestions on what you might do, I'm all ears.

Hey Justin,

My first response would immediately be to turn your control room 90 degrees clockwise, so you're facing the logo wall. There's this thing about using rectangular rooms "un-rectangularly" (is that even a word? You probably know what I mean... my bad... English is not my mother tongue). Furthermore I'd suggest you take a look at the wealth of information HERE for you'll find a zillion projects and usable layouts there if you want to tune things up.

Good luck, and keep the pics coming!

EDIT: Just found out you already found the John L. Sayers domain... you might want to update your profile there with your location... it's a critical board rule there.

EDO,

thanks for taking a look...

In retrospect that's the way the console should be facing. Unfortunately the furniture doesn't fit that way... it's just a bit too wide. So, without replacing it, I'm stuck.

It was one of the best budget finds I've ever come across.

Yes, the Sayers forum is quite phenomenal. I had mind overload this weekend (Thanks Frank!).

What KIND of work do you do in your studio?
For commercial and narration work, I don't hear an accoustic problem on my high quality monitors.
I don't hear anything that would keep you from turning out high quality work.

I'm with Bill... I thought it sounded pretty darn good, as-is.

Was there something in the existing sound that you were trying to change?

According to my "Room Dimension Calculator" the room should be cut down, that 24' section is causing a problem. For a ceiling height of 7'6" the room length should be between 9.8 feet and 21.7 feet (but not between 14.4' and 16')

The width of 12 feet is right on the minimum. (the calculator is from tmlaboratories.com)

I follow a 50/50 rule when sound treatment is concerned. 50 percent hard surfaces and 50 percent soft. It keeps the room from sounding completely dead and killing vocal performance. I imagine the sound bouncing around the room like a ripple on the water, Since I usually face one direction, the first piece of foam is on that opposing wall, and the next piece is on the wall that would have received the bounce from that wall. I also don't just use foam, but also incorporate a couple of wood diffusers and corner bass traps.

The guys at Auralux love to help, drop them a line and they'll run your room through their software.

Sounds pretty good to me, but here's a thought. Cut the room down as Monk suggested and use the left over space as your machine room for your computers.
The machine room will need some ventilation though. Just a thought.

Here's an update on the room acoustics project. I'm in the process of building about 20 traps and gobos and a couple of resonators... There are images in my photoset at Flickr...

http://www.flickr.com/photos/jrkaiser/sets/72157617280297733/

Thanks to everyone that helped with this project and the feedback that I was privy to. Specifically Frank Frederick, the VO-BB crew, Gary Kline, and my engineer and friend Mark Spalding.

Also, a special thank you to Joel Dubay for providing some valuable insight and the plans at http://www.basstraps.net/DIY-BASS-TRAPS-MADE-EASY.pdf

Total cost of materials for 20 traps was about $300. If I were to buy them commercially I'd spend over $2000 at today's rate. In the future though, I might think about fabric covers from http://www.readyacoustics.com it would save the hassle of trying to get the fabric nice and tight, but would increase the price significantly. I was able to get the fabric at $1.50 a yard after a 50% off coupon at JoAnn Fabrics.

The design of these will be adapted to ceiling clouds and gobos for the Iso booth and the main studio. In addition, I will be working on some tube traps and a couple of Helmholtz Resonators.

I still need to trim up the inside fabric, put wire on the eye hooks for hanging, and put the 5 inch 1x2 on each corner for wall spacing. I think I'll have about 60 minutes into each one by the time I'm done. I can probably get it down to 45 minutes with some effort, but I'd be better taking my time,

Thanks again guys for the help!

Thanks Bob! I've found after constructing that they are a bit top heavy because I mounted them higher than originally planned. I just mentioned to Frank that I'm going to drop by Menards or Lowes or Wal-Mart and pick up a couple of yard pavers to add weight to the bottom.

Also, constructed a platform for my new hobby... Like I need another one of those...

Heading in to get cleaned up and enjoy the rest of the afternoon with my family...

To you and yours Bob!

Well done and looking good!

I have sent you some thoughts on building Helmholtz Resonators which might be of use.

Toodles

Received... any good tips on hanging the 2x4 panels from the drop ceiling... They're not that heavy... 15 pounds each maybe... do you think the ceiling can support that? I'm kind of at a loss on this one.
