There's a stop on the lower cam that hits the cable (Hoyts back wall). It does make a noise. I don't think it is any louder than the quitest clothing movement and it could be silenced. I can pull one without making it. I think it is caused by a sticky cable where it hits the stop. It's not like plucking a rubber band it's more like rubbing a streched one. Try some powder where it touches. The velcro on my release (I know) makes more noise.
