vocal booth construction

I'll will soon be closing the deal on my house and the first thing i want to do to it is build a vocal booth. Years ago i had one of those music mags that had an article with step by step instructions from start to finish,it even had materiels listed from low budget to expensive. Its been so long ago that i can find it or even remember which mag it was. Does any one have any resources that they can direct me too that will give some blueprints for sound proof booth construction?

The type of noise you are trying to reduce/eliminate will greatly affect the cost. Is this a booth near a control room or a setup for a band? Do you need to see in/out of it or can it essentially be a box with a door?

Hey man,
Congrats on the house...!

What are the reasons that you want to build a vocal booth ?
Also what are the maximum dimensions the booth can be ?
Is isolation from load sources (as mentioned by poundaproblem ^) an issue ?
What is your budget ?

Sometimes building an iso booth isn't necessary if you could do with recording in the control room with cans on.
I say this because a lot of times people build themselves a booth which is so small and lacks treatment that it doesn;t enhance the sound of the vocals they want to record...and causes all sorts of nasty artifacts to the recording....

But even with limited space you can make it work, although you;d have to try and make the booth as dead as possible for usable frequencies in vocals around 125 Hz and up...and add reverb later artificially if needed...
If you're building a small booth usally you don't have enough space to work with any desireable reflections, so on the inside try to absorb down to frequencies as low as 125 Hz evenly...instead of just putting cheap foam on the walls..what alot of people do...which only affects the high frequencies and doesn't do anything for the mid-lows and lows..
These lower frequencies will reflect from the booth walls / ceiling etc.. and could create nasty reflections and comb-filtering.

This can be dealt with quite easily by placing broadband absorbers on the walls / ceiling of the booth or constructing the inside walls so that they function as broadband absorders... This can be done with rockwool isolation covered in fabric... this depends mostly on budget and space

Also if possible, construct a booth without any parralel surfaces, this will help with the above mentioned issues also...

Anyway, sorry for the long post... hope it all works out...
