Actually would be a lot quieter, since the turbine wouldn't have a high velocity exhaust output. And the fans are fairly quiet.
One real advantage would be quick throttle response. Gas turbines are slow to ramp up output power which is a real problem when dealing with wind shear on takeoff and landing. A 30 knot wind shear turns your 140 knots air speed turns into 110 knots airspeed. An electric fan's response would be very fast, probably faster than a prop plane.
