First, the noise level is low.  Nothing that's going to drive humans crazy.  Second, the Wiggly Giggly Ball is everything it promises to be.  Tough, makes low-level noise, and requires no batteries.  Love that.  Though my current dog didn't go bonkers over this ball, I've had dogs who loved batting them about.  My dog is into noisy toys but not balls so much.  But I'd still recommend the Wiggly Giggly Ball for its quality and durability.
