調整装置。It comprises a base that is attached to the inner surface of the room, a sound reflecting plate formed to have a width that is approximately the same as the width of the base, and two sound absorbing plates that are formed to have a width that is shorter than the width of the base. In this structure, one side end of the reflecting plate is horizontally rotatably pivoted to one side end of the base, and one of the two sound absorbing plates has one side end attached to the base. The other sound absorbing plate has one side end thereof pivoted to the other side end of the reflecting plate so as to be horizontally rotatable. The other side ends of the two sound-absorbing plates are pivoted so that the two sound-absorbing plates can horizontally rotate between being in a straight line and being folded on the back side of the reflecting plate. Device.
