In my case the when the valve opened it would be hammered with too much
pressure, bouncing back and partially closing. At the right pressure it
would oscillate. Since turning on the sink solves the problem this may
be cause. Sounds exactly like what happening here. Turning on the sink
reduces the pressure and the noise stops. John's case I would run the
dishwasher and while it's making the noise start closing the shutoff
valve until the noise stops.
I always cut back the shutoff valves to the toilets, dishwasher and
clothes washer to avoid surprises in the shower. Only down side is
slower fill times.
