I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">louder</span>' is the definition.<br/ ><span class="explanation-format__explanation">('noisy' is associated in meaning with 'loud')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for noisier that I've seen before include "More rowdy" , "More loud" , "Louder" , "more deafening!" , "Perhaps more disturbing" .)
