There has been talk this year at Wimbledon of umpires cracking down on the loud shrieking by some of the women. I would like an opinion on this - is there a difference between a grunt, and a squeal? I don't mind a healthy Williams scream, but I have to hit the "mute" button when Azarenka or Sharapova take the court. They emit a high-pitched squeal, not as they hit the ball, to add power on the exhale - but after. It's an annoying, ear-splitting sound that's like fingernails on a blackboard!!! Does it really help their game, or is it a sound they make to psych out opponents?
