I would check the draw lengh adjustment for loose screws. I know that once my bow's draw lengh adjustment screw fell out and made a noise.
Thats what I think it may be as well. Parkers and Bears are prone to this as much or more than most. Not a big deal, just something to keep and eye on.
Did you notice any difference in noise on the shot? Did it get any louder or anything like that on release?
