Can you pin-point the cause of the noise? That will help to determine what needs to be done to fix it.
One thing that will help any bow is work on your release. The better your release, the quieter the shot.
A well made string will generally be quieter than a poorly made one, regardless of the material.
Silencer placement is as important, if not moreso, than silencer material. Do a search on "heterodyning".
If you use cat whiskers, don't leave them too long. They will slap and make their own noise. Wool puffs left too long make a pop, at least on some bows.
Make changes in small increments. I've found short bows to be more finicky when it comes to tuning. If you over-adjust you may miss the sweet spot completely.
