Row resounding in one's head (5)
I believe the answer is:
skull
'head' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for skull that I've seen before include "Bony frame of head ..." , "Cranium" , "Pirate flag feature" , "Head bone" , "Head structure" .)
