I have questions... help me!

Hi buddies:
I am a fresh graduate and on my first job working on the noise and vibration of the air conditioning. Now, I have some questions:
our R&D center recently set up three labs: a small anechoic chamber, a reverberation chamber and a listening test. The problem is that how to evaluate the these three labs. How can we know the qualification of them. Could you explain to me or any recommendation of any paper and useful website?

P.S: does anyone work on the similar field?
Thanks a lot

Probably you can look into ISO 3740 until 3746,which will throw info into anechoic chamber qualifications
