I don't think we're quibbling about the fact that a "Racket" is a noise, just the way to spell the word for a piece of tennis equipment. I think this clue is looking for the name of something found on a tennis court which sounds like a noise; unfortunately both "Racket" and "Racquet" fit the bill.
Agreed it could be either but I took the defining word to be 'noise' and the normal crossword answer for that is racket. So I guess it depends on whether it's a 6 or 7 letter answer
Racquet .. 22,25,12,21,7,6,1 .. Z is 2 and V is 11. As the letter ‘A’ is usually common this helps set ‘25’ and usually only 1 ‘Q’ .. and there is only one ‘21’. Enjoy your day ..
