RE: Anechoic Background Levels
You also have to be very careful about where you measure the noise - if you hve any ventilation or whatever then things get complicated very quickly.

I was thinking that way too, but wanted to make sure I met Stds if there were any. Anyway, always good to confer with another engineer before telling the boss you're going to spend a lot of money.

We certainly didn't meet 20 dB at all frequencies of interest.

I'd recommend Eckels, and I'd strongly recommend against Industrial Acoustics who have gone downhill since Martin Hirschorn sold the company.
