The sound is present for all air gap faucets and basically is a side effect how they work that you can't really get around. While physically possible to bypass the faucet by disconnecting the two waste water lines and connecting them with a 3/8" to 1/4" union that isn't really advisable as you would be bypassing all the safety features that you have the air gap faucet for.
