After 12 years no noise, our pipes are singing. It can happen on any
fixture. Not real bad, just enough to notice. Same with our next door
neighbors who have a separate water service.

Plumber friends suggest prv, so I call the City Water Dept., they come out, and say you don't have a prv, because your main supply is only 55psi at the hose bib. Everyone is stumped as to what the cause is.

may be something stuck in main shutoff.....run water at a fixture go to main shut off and turn it off slowly..see if noise pitch changes or stops...

Did you leave a hose bibb with a vacuum breaker in the on position with the hose charged?

That can cause it.
