Sounds made by hooters about one (6)
I believe the answer is:
noises
'sounds' is the definition.
(noising is a kind of sounding)
'hooters about one' is the wordplay.
'hooters' becomes 'noses' (I've seen this before).
'about' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'noses' going around 'i' is 'NOISES'.
'made by' acts as a link.
(Other definitions for noises that I've seen before include "sounds unpleasant" , "Sounds, rackets" , "- - Off (stage farce)" , "Unmusical sounds?" , "Disturbing sounds" .)
