Hi Carlette, At GGNS we use a computer file of recorded plant noise. We use our WBC room and play it back over amplified speakers. We keep a decibel meter available to check that the level is at least 90 Db. Usually the door to the room is closed and it is very low key during our normal office routine.

Any information on your process would be most appreciated. Thank you for your time Carlette Barnhill Senior RC Specialist- Dosimetry/InVivo InVitro Bioassay/Respiratory Protection Progress Energy-Brunswick 910-457-2453
