vocal isolation booth 1.8
Here we start with a row of 2-inch foam with bass traps wedged into the corners. Low-end frequency likes to hide in the corners and build up standing waves, which these traps help eliminate. The pattern was alternated around the isolation booth to within 11 inches from the floor. Another bass trap was placed on the opposing wall where the back wall and door-side wall meet.

Almost done, and….

Done… The tree is trimmed, the turkey is ready and the stockings are hung with care…
With the quick addition of the Neumann TLM-103 and the copy stand, we are ready for some work in a completely sound isolated voice over booth that stands up to or rivals any isolated audio recording environment out there. The only thing that might have it beat is a scientifically designed, acoustically treated anechoic chamber, but how many people have one of those lying around?

The sound isolation booth is now the multi-functional environment we had always hoped it would be. Because of ISDN, we patch a lot of international interviews with foreign correspondents for the BBC and other radio shows. When they pipe in people from our studio you would be hard pressed to tell that they aren�t sitting right next to the show host. We have a sound environment that the big boys like when they hire voice talent, and ultimately the audio signal captured inside this booth is far cleaner and far quieter than many clients have ever asked for, or could have thought possible.
For questions, comments or further elaboration on any detail of this project please place your questions and comments there.
We hope you enjoyed this little tour and we welcome your thoughts regarding it.

Hi Guys
I must thank you, as I am new to home recording having always paid for and used pro studios for my voiceover..so I certainly am a novice in home recording. I have been looking for ages on a step by step way of building a vocal booth in my home…and yours certainly seems great.
I’m no carpenter/electrician or DIY enthusiast but i,m going to give it a go.
Cheers

Hey Guys…
Thanks so much for posting this information. When I built my home studio I had decided to purchase a whisper room. The whisper room does keep most of the outside noise out but inside the amount of bass that my voice creates makes for an unhappy recording. Bottom line is I decided to sell my whisper room which is probably great for other types of voices and build my own booth. I was wondering what your thoughts are about the size of the room I should build. Fortunately I have a space about 7 to 8′ wide by 6′ long and ceiling height about 11 or 12′ feet. My whisper room is a 4′x6′x7′ ceiling height. Any thoughts on what size I should build??
Thanks
J
Given that size I would go with outside dimensions of 8 wide – 6 long and 8 high – imagine it as a box and then cut one corner off – so that you have nothing but odd angles inside the booth.

I have a couple questions I was hoping you could answer. I’ll be constructing something quite similar to your booth for a studio next month, and I wondered if you could list the actual products used, the rubber fiber and the other isolation materials. Obviously not the wood, sheetrock, etc, just the brands for the isolation.
Also, how many hours/dollars did he project rack up? It’s a tremendous room and, at -80 dB, probably one of the best in the area! Thanks for the detailed walkthrough!
The rubber fiber mat – the best I can do – is that it is an interlocking, closed cell fiber mat that is used for gym floors. It looks like large uniform jig-saw-puzzle pieces and came from home depot. They also market it as soft flooring for children’s play rooms. The foam is all Auralex.
Once again – hours – I don’t know if I can be more accurate than MANY. I recall this booth was in the 1600 to 2000 dollar range. That includes all the wiring and foam.
Thank you for such a great write up, do you have this on a pdf file so that I may print it out and have it available with me when I go shopping for the materials.
Thanks,
Ben
As far as a printable PDF? No – but that’s a good idea… You start looking for the donation button and I’ll start looking for the PDF…
Hi Guys,
I’ve read and re-read your build many times. On 10/11/09 My builder is starting on my room. I ended up selling the whisper room and I’m quite excited to get my room built. I decided to build a 7′x7′x9′or10′high room, basically using your build as my bible. The one question I’m still hung up on is the pass through for the cables. I understand how you did yours, but I truly want to have a pass through, because I’m not even sure what or how many cables and different devices I’m going to put in the room. I saw this pre-fab pass through on line from some audio company but they want like $427 bucks for it. It has 2 hinged doors and memory foam that seal in the cables. Any thoughts???
Thanks
Jasen
We discovered that having so many cables in the room was a waste. Any gear in the room will turn it into a furnace – and installing ventilation to make up for the gear just adds to the problem.
We’ve wrestled with the pass-through as well and we stuck with the same method (albeit less cables) for our second build.
I don’t know which pass-through you were looking at – but $450 is pretty heavy. I would think an adequate one could be soldered for less than 200. That is of course if you want to go through the expense and effort. We just bought really long, high-quality cables (gold-tipped Blue) and ran them through the wall.
My fear with a soldered pass-through is and always has been its susceptibility to RF interference. We have a radio station down the road that came through some of our solder work once and we changed it all out. Just food for thought.
Hi guys, I have been reading the post and it’s very interesting. I bought a demvox booth past year and I’m very happy with it, but this monster sound isolation booth is Amazing!!!
