Yeah, turbochargers run at much higher RPMs than superchargers, so
most of it's noise is above the normal human hearing threshold. They
bug dogs more than humans... ;-)

The idea is the same - use a turbine to pump more fuel / air mix into
the engine at higher speed. The supercharger runs off the crankshaft,
and the turbocharger runs off exhaust pressure. Superchargers are less
fuel efficient, but they provide more power and provide it faster than
turbochargers (turbochargers always have a "lag time" while the
pressure builds up, superchargers come up to speed as soon as the
engine does).
