TURBO NOISE - Sounds like a foghorn - thoughts??

Greetings - Have a 2002 9-5 Aero w/ 100K miles (live in Maine)
Just began noticing this one over the weekend:
When accelerating in sport mode under mid-range RPM, I notice this foghorn like sound from the engine compartment...determined the sound starts when the boost gauge on the turbo hits the second stripe, then backs off when it goes below. Press the gas, get the boost over the second stripe, same thing, low frequency humming/foghorn like noise. I am guessing this is turbo related?? Any thoughts/help would be GREATLY appreciated as I'm bringing this into the dealer for a scheduled 100K service and would love to know what I'm up against prior...
Many thanks
