Studio build from ground up (parallel walls question)
Hi all GSers,
I'm hoping some of you will have an opinion on this.
I do some lecturing for a College which is just about to go through a big programme which involves building the new College from scratch.
Currently, they have a fantastic studio facility, with all live rooms and vocal booth that have non-parallel walls. The company that built the current studio was very specific saying that this would break standing waves, and reduce resonance issues. And in my opinion the current rooms definitely do a great job, particularly the large vocal booth (great sound).
Anyway, the acoustic consultant for the new build said that "putting parallel walls in makes very little difference, anyway bass traps and absorption will do the trick". I think he is just saying that because it costs more to put the parallel walls in. Also, if you are building from scratch, best to get it right before you put the absorption and acoustic treatment in. Right?
The College has said the new build should be AT LEAST better than the current studio, and I am concerned that it won't be. So
1 - Does anyone have information I can use which proves or dis-proves the need for parallel walls?
2 - Or has acoustic treatment come on so much in the last few years, that treating an oblong-shaped room with traps etc. will do just as well
Thanks for your input all.
