When I turn on the shower in our newly bought home (12 years old), the shower howls. However, if you reduce water pressure to about 1/2 flow, the howl goes away. Any suggestions on how to fix it?

Some folks arbitrarily install piping scratching their heads and saying
"Golly last time I saw 1/2" copper installed I reckon it would be good here to"
What they do not take into consideration is the incoming pressure and the velocity associated with it.
Many people confuse volume and pressure and installing under sized piping or allowing to much pressure will cause all sorts of problems like hydraulic shock, piping erosion if the velocity on cold water in copper exceeds 8 FPS and 3 FPS on hot water..
The "throttling" down of the shower is exactly why Globe valves were designed for.
You can try checking the shower head for possible sediment in the flow restrictor or mineral deposits restricting the flow and causing a velocity condition
