Wont be possible with that bow. Do the best you can with the advise above and try and make the rest a common noise heard in the woods. Shot for a gust of wind type noise, not a loud crack. The right arrow weight like tfox mentioned and string supression might do the trick.Make sure everything else (acc.) is quiet.
I agree, but something you can try is removing one accessory at a time to see if that is the problem. Bow quivers are notorious for making noise, especially since they are made of plastic. If it's the quiver it's possible a limb saver or two will help, but I just remove mine when on stand as do most people I talk with.
If you can do the string Leeches thing then good old Catwhiskers always do a good job.
