Noise or disturbance can be wearing (7)
I believe the answer is:
erosion
'be wearing' is the definition.
(I've seen this before)
'noise or disturbance' is the wordplay.
'disturbance' is an anagram indicator.
'noise'+'or'='noiseor'
'noiseor' with letters rearranged gives 'EROSION'.
'can' is the link.
(Other definitions for erosion that I've seen before include "Mechanical process of wearing something down" , "Abrasion" , "The wearing away by weather 97)" , "Action of wearing away" , "A wearing away as of rock by water" .)
