A lot of tennis-players grunt with effort upon striking the ball, but the fetching 6′ 2″ (188 cm.) Maria Sharapova produces a veritable kiai, which the Melbourne Herald Sun measured at “71.5dB — louder than a vacuum cleaner (70dB) and approaching the level of a power drill (80dB).”

Little do they know in Melbourne that, at Wimbleton in 2005, Sharapova was measured reaching 101 db, almost as loud as a police siren!
