5. Serena Williams
The younger of the Williams sisters has been clocked at 88.9dB. This level of noise is louder than a food blender (88 dB).
4. Monica Seles
Surprisingly down in fourth place, Monica Seles invented “The Grunt”. At 93.2dB, this is the same noise level produced by an electric drill. No wonder her opponents felt like she was drilling a hole in their heads.
3. Victoria Azarenko
The Belarusian has been recorded as high as 95dB, the equivalent noise level you would be subjected to standing next to a subway train.
2. Maria Sharapova
The darling of the grunters, Sharapova’s record shriek was measured at 105dB. To get an idea of just how loud that is, stand about 3ft away from a chainsaw.
1. Michelle Larcher de Brito
Portugal’s finest tennis player is also the world’s loudest. Larcher de Brito has been clocked at an ear-splitting 109dB, almost as loud as a lion’s roar (110dB).
