RE: hoyt mt-sport
Ditto on nearly every point made by the several responders. My MT Sport is VERY quiet. Its outfitted with the above mentioned split limb noise reduction system, string whiskers and I shoot a heavier arrow/broadhead combination. The arrow weight will go a long way to reduce the noise of your bow. Don't go to a great deal of expense but just try a heavier broadhead and see if that helps.
