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.
