'extremely loud' is the definition.
'earsplitting' can be an answer for 'loud' (similar in meaning). I'm not certain of the 'extremely' bit.

'doctor plastering it' is the wordplay.
'doctor' indicates an anagram.
'plastering'+'it'='plasteringit'
'plasteringit' with letters rearranged gives 'EARSPLITTING'.

'is' acts as a link.
