Exactly what Andy said, make sure the string is waxed real well!!! I had the same problem with a new bow and tried everything but wax and as soon as I waxed the strings and cables, whala, nothing but dead quiet. A dry string will vibrate like heck. I also added the STS afterwards and put on cat whiskers instead of the bowjax that come on the string. Cat whiskers work better than anything I have tried to date and now the bow is the quietest I have ever owned and put up against some of the leading bows out there a better shooter in my eyes. Oh, by the way, it is a Pearson Stealth!!!
