Precisely - Ducted Fans are still around it's just that they are electric powered and believe it or not they do have a sound all their own.
Glow Ducted Fans were just irritating sounding but electrics sound a lot like air moving but the fan also makes quite a pitched whine - like a much less throaty turbine (or a turbine with no balls if you will).
Small EDFs are extremely popular.
