Elena Dementieva claimed she was distracted by Maria Sharapova's on-court grunting during her defeat to the former Wimbledon champion.
Sharapova has been repeatedly asked about her on-court noise
Sharapova won their quarter-final clash 6-1 6-4, but Dementieva was unhappy with the noise levels on Centre Court.
"Personally, I think it's a little bit too much, but that's the way she's been playing for a long time and the tour has allowed her to do such a noise.
"I think the umpire should step in and make her come down a little bit."
Asked if she would speak directly to Sharapova about the issue, Dementieva said: "I think the best way is to beat her, not to tell her what to do.
"It doesn't bother me but I think it's too much. Next time I beat her I will say something."
Sharapova was unconcerned by her fellow Russian's comments.
"I don't worry about that, that's her opinion," she said.
And Sharapova was bullish when asked how she would respond if told to tone down the noise.
"I wouldn't change a thing," she insisted.
