Gads about with the big noises (7)
I believe the answer is:
rackets
'noises' is the definition.
(racket is a kind of noise)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rackets that I've seen before include "Walled-court ball game" , "illegal activities" , "Organised crime" , "Stringed bats or loud sessions" , "Those taken to court" .)
