Abstract

The invention relates to a layered material for influencing the vibrational, radiational and/or tonal behaviour of particularly flat sound-radiating elements. Said layered material comprises at least two layers which are disposed on top of each other and joined together, each layer consisting of parallel or angularly disposed bar-shaped support elements (1, 2) whose initial and the end points are joined to other support elements or installed in a sound-radiating element and connected thereto.
