'environment become dull' is the definition.
I can't judge whether this definition defines the answer.

'caught in excessively noisy' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' is an insertion indicator.
'excessively' becomes 'over'.
'noisy' becomes 'loud' (associated in meaning).
'over'+'loud'='overloud'
'c' going inside 'overloud' is 'OVERCLOUD'.
