The present disclosure relates more particularly to a plaster wall panel including a first plaster layer, a second plaster layer, and a damping layer disposed between the first and second plaster layers. The first plaster layer has a first thickness and is composed of a first plaster material that has a first material property. The second plaster layer has a second thickness and is composed of a second plaster material that has a second material property. The first thickness is smaller than the second thickness, and the first and second material properties are different.
