Noisy confusion of voices (5)
I believe the answer is:
babel
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">noisy confusion of voices</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for babel that I've seen before include "pandemonium" , "Confusion of sounds" , "Tower built by Noah's descendants to reach to heaven" , "Place of cacophony" , "Noisy confusion of voices" .)
