Bing, bang or boom (5)
I believe the answer is:
noise
'bing bang or boom' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for noise that I've seen before include "Kind of pollution" , "Confused sounds" , "Unwanted sounds" , "Loud sound; bruit" , "Sound, disagreeable perhaps" .)
