Part of window can be a nuisance, we hear (4)

Ross

I believe the answer is:

pane

'part of window' is the definition.
(I know that pane is part of window)

'a nuisance we hear' is the wordplay.
'a nuisance' becomes 'pain' (synonyms).
'we hear' shows a homophone (sound like).
'pain' sounds like 'PANE'.

'can be' acts as a link.

(Other definitions for pane that I've seen before include "Piece of glass in window" , "Panel of glass" , "Single sheet of glass in a window" .)

I've seen this clue in The Mirror.
