I hear a slight "twang" as well.

I have had people tell me that they think my bow is quiet as well but I never had anyone shoot it while I stood back and listened. I don't know anyone with my draw length

I think because the string is so close to your ear, there is no way youwill eliminate the sound of the string (or loop) leaving the release. I believe that isthe "twang" sound you are hearing.

Try shooting with your fingers once and see if you still hear it.

Too Funny!!
