Re: Noise level - NC and dBA
I don't think that link gives a proper answer to the question. Just the basics to hearing.
Any more takers?

This may help you. It's about sound testing for Cooling Towers but does have some definitions and a lot of reference material.

NC = Noise Criteria
Which I believe is the noise level required by the specification/designer.
