Clank or creak (5)
I believe the answer is:
noise
'clank or creak' is the definition.
(I know that clang is a type of noise)
This is all the clue.
(Other definitions for noise that I've seen before include "Loud or unpleasant sound" , "Unwelcome sound" , "Static - sound" , "Row" , "Loud sound; bruit" .)
