It may help a bit, but prob won't fix the issue completely, an idea could be to fit a extra air tank to the system as a storage tank if your mechanically minded (I use old gas bottles but they do need to be rigged with a safety release valve and a bi directional inlet/outlet system..Alternatively if you have some tyre tubes hanging around you could blow one up with your pulsing compressor and then attach your hose to the tube valve and the pressure will be constant, if you have an older styled hand pump, you can use the screw on hose of these to jerry rig your air brush to the valve (till it deflates the tyre tube of course, ie the tubes just a basic storage tank but again it would take a redisign on where ya place your regulator and water trap so it comes in after your storage vessel..Easiest way maybe is just buy a cheap tanked air compressor if noise isn't a huge issue...Good luck..
