Reverberation of snore disturbed a new church (9)
I believe the answer is:
resonance
'reverberation' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'snore disturbed a new church' is the wordplay.
'disturbed' indicates an anagram (the order of letters is disturbed).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'church' becomes 'CE' (abbreviation for Church of England).
'snore' is an anagram of 'reson'.
'reson'+'a'+'n'+'ce'='RESONANCE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for resonance that I've seen before include "Sympathetic vibration" , "Sonority" , "shaking" , "Deep, clear, ringing quality" , "Plangency" .)
