Cochlea location (5,3)
I believe the answer is:
inner ear
'cochlea location' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for inner ear that I've seen before include "profound listener" , "Part of hearing organ" , "Auditor's part" , "vestibule and what it leads to" , "Part of the auditory system" .)
