Amazing how you could get them little guys to fart on cue like that for testing....
Feed 'em beans and point your bow at them!
What'cha doing, specifically?
First thing I do is attach the typical Sims products, including limb savers (sometimes 2 sets), string leeches (or cat whiskers), teflon cable slide and cable dampener. I then put a thin layer of rubber between all accessories. - no metal to metal contact anywhere on the bow. The cat whiskers go on both the string and the cable. The cable dampener is set so the slide hits it on return, helping to deaden any vibration from the slide. I never use a bow quiver. They are too noisy for my tastes.
I then put on a custom string that I build. For some reason, my strings are quieter then any I've ever received with a bow. My rest is the new whisker biscuit, which is the quietest rest I've ever used. My release is a Tru Ball and makes no noise upon release of the arrow. I always shoot around 7-8 grains per lb of draw weight, which helps a lot. Test each stabilizer with the bow you are putting it on. Not all work equally well with all models. I do not use anything on the string except a Catfish loop. No peeps, brass nocks or other heavy items that will produce more string vibration and more noise.
In the past, I've played with putting rubber material in the limb pockets, but most new bows are protected in this way now. I always disassemble the bow and put silicone based grease in the limb pockets and dry lube on the axels. I don't want any unexpected squeaks (other than from the mouse), when I'm drawing on an animal.
I've owned several bows in the last few years (all from different manufacturers), and no matter which one I'm shooting, I frequently get comments that it's "the quietest bow I've ever heard". One was a Martin Panther, which was only $285.00, new. You don't need to spend a lot of money to have a quiet hunting bow. You just have to pay particular attention to making the one you have, shoot quieter then when you bought it.
