I took some readings with an iPhone DB meter. Who knows how accurate it is, but it’s useful for comparison. Running a cheap black and decker router I had sitting around in the garage. Not cutting any material yet. I don’t have much sealing around the doors of the cabinet yet. And it seems like there some sound leaking from some areas. I think I can make some slight improvements. I’ll retest once I’m cutting material – probably a couple of weeks from now. See attached photo.
