Loud and resonant, it's exploding (10)
I believe the answer is:
stentorian
'loud' is the definition.
('stentorian' can be similar in meaning to 'loud')
'resonant it's exploding' is the wordplay.
'exploding' indicates anagramming the letters.
'resonant'+'it'='resonantit'
'resonantit' anagrammed gives 'STENTORIAN'.
'and' acts as a link.
(Other definitions for stentorian that I've seen before include "booming" , "Strident" , "(Of a person's voice) loud and powerful" .)
