The ones that involved one in the racket (5)
I believe the answer is:
Here is my best explanation:
'the racket' is the definition.
('noise' can be a synonym of 'racket')
'the ones that involved one in' is the subsidiary indication.
'the ones' becomes 'is' ('I' can be a synonym of 'one').
'that involved' indicates an anagram.
'in' means one lot of letters goes inside another.
'one' anagrammed gives 'noe'.
'is' inserted within 'noe' is 'noise'.
(Other definitions for noise that I've seen before include "Loud sound; bruit", "Disturbing sound", "Sound - gossip", "Hubbub", "Static - sound", "Unwanted sound", "Sound, disagreeable perhaps", "Sound of any kind", "Excessive sound" and "Clatter".)
