Share 'Looking for a quiet Air Brush Compressor'

I am looking for anyone with personal experience on QUIET air compressors. I currently have a very LOUD little rectangle (when my son was sleeping he thought it was a lawn mower ). Since I am a hobby decorator I do all my work at home so there is no ambient noise and this little 3"X5" device just isn't working out.  I have seen a few online that show 47 decibles but I am not sure if that is quiet…
