In Reply to: Just how rare or expensive is an anechoic chamber? posted by riker1384 on January 16, 2009 at 18:23:43:
I can answer this quite well I think because of SoundStage!'s use of one.
To build a chamber like NRC has would cost about $200,000 to $250,000 depending on where you're going to install it. The chamber's built as a self-contained unit, they hoist it up on springs, and it's placed at NRC within a very large building. So, think of it as a building within a building. The figure I get is from other companies who have built their own and have told me what it's cost them to do it.
NRC also has another feature -- a $100,000 air system that maintains proper temperature and is quiet enough for a lab. This, obviously, isn't an insignificant cost.
Chamber rental prices vary. Also, there are other chambers that you can rent. For example, the largest one I know of is in the same city (Ottawa) at Health Canada. It's like 6X the size of NRC's and supposedly "in-chamber accurate" to 20Hz. That's a HUGE chamber. It'll set you back thousands per day.
In know over in Britain the BBC has a chamber -- we were comparing plots with Alan Shaw of Harbeth with ones he's done there.
Commercially, the companies I know of that have their own chamber include Definitive Technology, Paradigm, Axiom, Harman (and all the companies that come under that umbrella), TAD, and API. There are, perhaps, others.
So, yes, in a way they're hard to come by -- but they are out there.
Hope that answers some of that.
