Unable to hear, some made a fuss (4)
I believe the answer is:
deaf
'unable to hear' is the definition.
(I've seen this in another clue)
'some made a fuss' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'DEAF' is hidden in the letters of 'made a fuss'.
(Other definitions for deaf that I've seen before include "Refusing to hear (entreaty)" , "Aurally challenged" , "Lacking hearing" , "Audibly challenged" , "Unable to pick up" .)
