I believe the answer is:

fall on deaf ears

I'm a little stuck... Click here to teach me more about this clue!

'no hearing' is the definition.
I know nothing about this answer so I can't tell whether this works.

'concerns after dodgy lad and a felon' is the wordplay.
'concerns' becomes 'fears' ('fear' can be a synonym of 'concern').
'after' is a charade indicator (letters next to each other).
'dodgy' indicates anagramming the letters (a dodgy or wrong order of the letters).
'and' means one lot of letters go next to another.
'a'+'felon'='afelon'
'lad' after 'afelon' is 'afelonlad'.
'afelonlad' is an anagram of 'fallondea'.
'fears' after 'fallondea' is 'FALL ON DEAF EARS'.

'get' is the link.

Can you help me to learn more?

(Another definition for fall on deaf ears that I've seen is " totally ignored".)
