Small vocal booth...advice?

[RobTob]

Hi

I want to build a small vocal booth (for narrative CD's) to basically cut out the tinnyness that seems to trail off my words and maybe absorb some of the lower bass freqs in the current larger room I'm using. Any ideas on good, inexpensive materials and booth dimensions would be vrey helpful.

I've been experimenting with foam (the sort that is used in exercise mats) and also comfort blankets and so far results seem promising but I wanted to get some more advice...

Cheers

Rob

Re Vocal Room

I.ve been experimenting for years at building recording rooms and vocal booths. I still use the dreaded 4 sheets of plywood hinged together. But the corners are now not square,Base builds up in the corners so get rid of the chances of this.. Some people cut all the corners at 45 degs. sound waves will still concregate exactly at centre of this room..as in the square corner room ...cut all corners differently,lets say 6 inches x 8 inches at the top of the room and at the bottom do the opposite and the exact centre will dissapear..People say my home built room is dead...I say not a change...wave sounds reflecting back are still present...Next I do not use foam .bedding material and such...I found the best cheap material is fibre glass batts...They are normally not covered...so I use mosketo netting to stop fibres falling off....Using foam and such material had a tendency to exorb all the richness and presence from my recordings....Fibreglass seems to remove what I don't want..and leave what I do want...I just finished a recording of three females doing hormonies and a baratone thrown into the mix WOW....I Finaly got what I was looking for...

As Mark said, fiberglass is the preferred material. Actually, rigid fiberglass is what's used most often.
