Not only do the visiting players have to get used to din inside the playing hall in Jakarta, but even home shuttlers are subject to the crowd's booing and yelling, especially when they are losing.
"They are so noisy. Often, their remarks are far from encouraging at all," national shuttler Maria Kristin Yulianti, who lost to Xie Xingfang from China in the first round of Indonesia Open, told The Jakarta Post on Wednesday.
Rizki Amelia Pradipta, one of Indonesia's young stars, said she could hear someone shout that she should go home while she was losing in her qualifying round match.
"From the audience, I heard a shout asking me to go home."
Sony Dwi Kuncoro said despite some irritating spectators, the crowd over all was still very supportive.
"I prefer not to be bothered with any of the spectators' yelling, and Just take everything positively," said the men's singles' fourth seed.
Men's doubles specialist Markis Kido said the cheering crowds fueled his fighting spirit.
"I get the heebie-jeebies hearing the spectators, but they are also my main source of fighting spirit," women's doubles specialist Anneke Feinya Agustine said.
Some may whine, some may praise, and others may just be indifferent to the country's loud spectators.
A fan, named Siswoyo, who has been coming to the championship since the qualifying round, take sympathy on losing players and urges fellow spectators to behave themselves.
"Some audience boo the players when they do not play well. I don't think it's fair," she said.
"When you support some players, you should support them all the way, not only when they're winning," said the 48-year-old from East Jakarta.
Indri Widyasari says she always opts for good manners when offering support.
"I prefer to cheer in a constructive manner, for example by clapping my hands, shouting the shuttler's name, and *Indonesia...Indonesia'."
"Rude statements should be avoided," the 18-year-old said.
Mimi Irawan, from the organizing committee, says the spectators can still control themselves.
"In my opinion, the spectators are still behaving normally.
"It is their full rights to make any kind of comment anyway."
"And it's absolutely natural, if one or two of the spectators turn to harsh language because they are disappointed by their players' bad performance," said Mimi.
Visiting players find noisy spectators distracting and annoying.
"Playing on the court, I need to concentrate.
"But it is hard to do so with such loud cheering from spectators, who stand too close to the court," said Zhou Mi, the top seed who suffered a cruel reversal of fate when she lost in the opening round.
Her opponent Sayaka Sato of Japan feels quite the opposite though, saying she was encouraged by the cheers from the local audience.
"The Indonesian audience has always cheered for me in all my matches in the past two days, even when I played against Indonesian players," she said.
"Thus, I really thank the Indonesian audience for being very supportive," said the 18-year-old, who is ranked 61st in the badminton world rankings.
However, it is not always the case when it comes to watching strong rivals like Malaysia and China play badminton.
"When I was young, they made me nervous, but it is not a big problem anymore as I have to face the same kind of cheering every time I play here," said Malaysian mixed and women's doubles player Wong Pei Tty, who has played in Indonesia numerous times.
"It is not my first time here. So, I am used to the rumpus."
