I believe the answer is:

murmur

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

'complaint' is the definition.
(I know that murmur is a type of complaint)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for murmur that I've seen before include "Low indistinct sound" , "Indistinct mutter" , "Little noise" , "Low background noise" , "Mumbled expression of malcontent" .)

I've seen this clue in The Sun.
