Orangeone, here is a post (post #63) from someone who has played against me. Everyone I have played says the same thing. They could hear the buzzing as the ball approaches them. All my serves have a lot of spin.
Here are some vids I posted today, so you could get a better perspective. As Fitzroy pointed out, you could really see the action on the ball.
