At different levels of play, athletes behave differently on the pitch.
From Sharapova's screams to Williams' yelling, you simply can't be sleepy in these races.
Why do they make such a loud noise? Let's take a look.
Some people, tennis players shout to scare off opponents, others think that this is just a release of energy in sports.
But for sports psychologist Louise Tilly, she thinks it could actually be a weapon in their game.
She said in an interview: "Tennis players shout and help the rhythm of their hitting. If they yell, they hit it harder, which will give you the confidence and feeling of control over the game. ”
On this tour, Sharapova makes the loudest noise, usually more than 100 decibels on the pitch.
Monica Cerres and Jimmy Connors roared, and Seles used to reach 90 decibels.
Both Sharapova and Azarenka have been criticised for the noise they make on the pitch, and while not everyone sees it as cheating, many experts and players are unhappy with the advantage this approach gives players.
There was a previous list of the five tennis players with the largest decibels.
5. Serena Williams
Number of decibels: 88.9
Her sister Venus' voice was impressive, reaching 85 decibels, but Serena's voice surpassed hers, as loud as a vacuum cleaner, and she spooked all her opponents.
4. Monica Seles
Decibels: 93.2
Monica Cerres was arguably the first player to do so, basically the head she brought.
3. Sharapova
Decibel count: 101
The Russian tennis player's shouts are as loud as a motorcycle, but the audience is not bothered to hear, but the opponent is often noisy and unintentional.
2. Victoria Azarenka
Number of decibels: 105
Playing against the former Belarusian world champion is like standing next to a hand-held rig and is indeed the best weapon to beat your opponents.
1. Mitchell De Brito
Number of decibels: 109
The Portuguese star made a sound as loud as a lion's roar, and opponents were timid when they heard the sound.
