When I moved into a denser neighborhood I traded out my small noisy air compressor for an old large one that operates very slowly. You can't even tell it's running from outside my garage, let alone outside my property. Even standing right next to it you can engage in normal-voiced conversation and no ear protection is needed. Unfortunately such machines no longer seem to be available new.
