Can anyone tell me how to reduce the interior fan/battery noise in the cockpit of the CRJ-200/700/900?I am using Christoffer Peterson's awesome sound set which is an improvement over the FT set, but it is still too loud for my taste. Respectfully,Scott

I think the AC fan noise comes from the panel itself and not the aircraft sounds in the sounds folder. Look in the "Feelthere" folder in your main FS9 folder and see if you can find the fan sound there. You can then reduce the volume with a wav editor. Hope that helps.Victor

If you turn the packs off on the overhead, the cockpit noise will drop. It doesn't cause any problems with the sim, but in real life you would want the packs on.Rick

AHHHH Victor was correct. I was looking in the wrond place for the AC sounds. All is right with the world now.Thanks!Scott
