Account for explosive noise (6)
I believe the answer is:
report
This clue is a double definition.
'account' is the first definition.
('report' can be a synonym of 'account')
'explosive noise' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for report that I've seen before include "Article" , "Formal statement" , "Complain about - account" , "result of firing?" , "Give an account" .)
