RE: Acousic Noise from ITE
Thanks for that update. I forgot to mention that the agency said that EN 27779 (ISO 7779) is the appropriate measurement standard.

RE: Acousic Noise from ITE
ETSI 300 019-1-3 AND Telcordia NEBS GR-63-CORE are standards that I've had to deal with. ETSI's requirements are considerably more stringent, and are quoted in bels which is a sound power (normalized to 1m^2) independent of distance. GR-63 measures sound pressure at a specified distance (0.6m from face and 1.5m height). This must be converted to sound power. Additionally, there's a 3dB factor that must be included in the calculation to account for statistical variations in manufacture. I know of some co-relation factors and a rule of thumb between measurements called for in the two standards.

RE: Acousic Noise from ITE
Rich, There us to be a series of specifications for noise equipment in office environments - not so much what type of equipment but more on the order of a quiet office environment equipment had to be 50 or 55 dBA, I forget which. Lots of nasty things to go along with all of that. Printers had impulse noise to contend with, etc. I don't know if they have, but the trend was to go from sound pressure measurements to sound power measurements. On the one had it made it easier for the manufacturer to make repeatable and accurate measurements, and you didn't need to have a sound anechoic chamber and make parallel piped measurements at various spots around the equipment. Been a while since I made those measurements, but Bruel and Kjaer had lost of papers on the issue.
