Seemingly noisy line? (3)
I believe the answer is:
row
'line?' is the definition.
(a row or line of things)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for row that I've seen before include "Altercation" , "Propel boat with manual aids" , "Line; squabble" , "File" , "Argument; tier" .)
