Whispering gallery, or Whispering dome, one of such a form that sounds produced in certain parts of it are concentrated by reflection from the walls to another part, so that whispers or feeble sounds are audible at a much greater distance than under ordinary circumstances. The dome of the U. S. capitol building is one example. [1913 Webster +PJC]
