I repeatedly snore — sadly making more din (7)

I believe the answer is:

noisier

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

'making more din' is the definition.
I can't judge whether this defines the answer.

'i repeatedly snore sadly' is the wordplay.
'i repeatedly' can mean two substitutions for 'i'.
'sadly' indicates anagramming the letters.
'i'+'i'+'snore'='iisnore'
'iisnore' with letters rearranged gives 'NOISIER'.

Can you help me to learn more?

(Other definitions for noisier that I've seen before include "more deafening!" , "More rowdy" , "More loud" , "Perhaps more disturbing" , "More of a racket" .)

I've seen this clue in The Times.
