Noted canonical hour, by the sound of it (5)
I believe the answer is:
known
'noted' is the definition.
('known' can be similar in meaning to 'noted')
'canonical hour by the sound of it' is the wordplay.
'canonical hour' becomes 'none' (traditional church service).
'by the sound of it' shows a homophone (sound like).
'none' is a homophone of 'KNOWN'.
(Other definitions for known that I've seen before include "In the public domain?" , "Recognised, familiar" , "Widely recognised" , "Acknowledged" , "Apprehended mentally" .)
