Noisy disturbances after this month's commands (12)
I believe the answer is:
instructions
'commands' is the definition.
('instruction' can be a synonym of 'command')
'noisy disturbances after this month's' is the wordplay.
'noisy disturbances' becomes 'ructions'.
'after' is a charade indicator (letters next to each other).
'this month' becomes 'inst' (I've seen this before).
'ructions' put after 'inst' is 'INSTRUCTIONS'.
(Other definitions for instructions that I've seen before include "Directions, orders" , "Directions; commands" .)
