音壁。A plurality of sound absorbing panels are hinged to each other in front of the indoor side of the reflective wall made of highly rigid structural material such as concrete, so that it can be folded freely. A folding wall is provided that forms an air layer to cover the reflective wall and is assembled in front of the reflective wall in a folded state, and each of the sound absorbing panels cooperates with each other in the folded state to fill the interior of the folding wall. A foldable variable sound-absorbing wall comprising a frame made of a sound-reflecting material forming an exposed surface and a sound-absorbing material placed inside the frame.
