Sounds (6)
I believe the answer is:
noises
'sounds' is the definition.
(noising is a kind of sounding)
This is the entire clue.
(Other definitions for noises that I've seen before include "Sounds, rackets" , "- - Off (stage farce)" , "Conventional phrases" , "Unmusical sounds?" , "Noses I turn up to sounds" .)
