The simple answer is it depends...
On a bigger copter it is most likely for added stability...
For something like an Apache (or Hind) it is more sound
dampening.  IIRC, there is some very complicated
Bournouli-type equation going on describing the turbulent
flow of the air around the rotors (and the speed at which
they move)

If you've ever NOT heard an Apache (or Hind) creeping up on
you, you'd understand the result...
