The invention concerns a wall element including a felt panel that has at least two felt layers, with at least one felt layer having a three-dimensional structure on at least one top side. The felt panel includes as its top layer a plane felt layer, as its bottom layer a plane felt layer, and as its middle layer at least one corrugated felt layer. The corrugated felt layer bordering on the top layer is connected to the top layer on its top side in the region of upper vertex lines or vertex points formed by its wave peaks. The corrugated felt layer bordering on the bottom layer is connected to the bottom layer on its bottom side in the region of lower vertex lines or vertex points formed by its wave valleys.
