Sharapova's on-court grunts have been measured at 102.12 decibels- apparently as loud as a police siren.
Hehe, I used to play at the tennis club that Sharapova practices at quite often. It's Lindsey Davenport's club in Newport Beach. She is definitely quite loud even when she is practicing. It's a pretty cool place to play, you can watch many men and women pro tennis players on the practice courts if they play in the ones with stands.
