Some dogs' noise disappears! (7)
I believe the answer is:
dingoes
'some dogs'' is the definition.
(I have seen 'wild dogs' mean 'dingoes' so perhaps 'dogs' could also mean 'dingoes')
'noise disappears' is the wordplay.
'noise' becomes 'din' (din can mean a loud noise or disturbance).
'disappears' becomes 'goes' (going is a kind of disappearing).
'din'+'goes'='DINGOES'
(Other definitions for dingoes that I've seen before include "Australian wild dogs" , "Australian pack" , "Cairns must live with these dogs" , "Wild dogs of Australia" , "Canine predators" .)
