Despite winning his second round match against Marcel Granollers in convincing fashion, Andy Murray has since complained that he could not hear the ball during the encounter which took place under the closed roof of the Arthur Ashe Stadium.
Murray was sublime as he dismantled Granollers 6-4, 6-1, 6-4 to book a meeting with Paolo Lorenzi in round three.
Surprisingly, though, the Scot revealed after the match that he struggled with the noise that seems to be kept inside the stadium now that the roof covers it.
Interestingly, Murray also highlighted the importance of being able to hear on a tennis court as it improves anticipation.
"You can't hear anything," Murray remarked.
"You could hear the line calls, but not so much when the opponent was hitting the ball or even when you're hitting the ball.
"It's not just the eyes, it's the ears, it helps us pick up the speed of the ball, the spin that's on the ball, how hard someone's hitting it.
"If we played with our ears covered or with headphones on, it would be a big advantage if your opponent wasn't wearing them."
Each grand slam has its own unique culture.
Wimbledon is traditional and proper, Roland Garros is often hostile and gruelling, the Australian Open has a slight carnival feel to it.
While colourful and always fun, the US Open is synonymous with constant noise from the crowds… even during points. Spectators are often seen having uninterrupted conversations with each other throughout matches.
The advent of the roof that now covers the Arthur Ashe Stadium when rain falls might call for a change to all that if more players complain of similar problems to the ones Murray experienced on Thursday. Easier said than done, though, the US Open does take place in New York after all!
