Noise belts out that's apparent (10)
I believe the answer is:
ostensible
'apparent' is the definition.
(I've seen this before)
'noise belts out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'noise'+'belts'='noisebelts'
'noisebelts' with letters rearranged gives 'OSTENSIBLE'.
'that's' acts as a link.
(Other definitions for ostensible that I've seen before include "Supposed" , "Manifest" , "Apparent" , "Professed" , "Seeming" .)
