<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">capable of being heard</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 audible that I've seen before include "Capable of being heard" , "Able to be heard" , "not to be missed?" , "that one can catch" , "Loud enough to be heard" .)
