Is at the centre of denials of annoying sounds (6)
I believe the answer is:
noises
'sounds' is the definition.
(noise is a kind of sound)
'is at the centre of denials of annoying' is the wordplay.
I cannot quite understand how this works, but
'is' is found in the answer.
'of' could be 'o' and 'o' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for noises that I've seen before include "Spreads abroad with sounds" , "Sounds like crackles" , "- - Off (stage farce)" , "Disturbing sounds" , "Conventional phrases" .)
