Report interference? (5)
I believe the answer is:
noise
I believe this clue is a double definition.
'report' is the first definition.
(a report is a loud sound like an explosion)
'interference?' is the second definition.
('noise' can be a synonym of 'interference')
(Other definitions for noise that I've seen before include "Virgil's birthplace" , "explosive report, for example" , "Static - sound" , "Unstructured sound" , "Hum" .)
