Dependent claims

A ceiling panel assembly, comprising:

a sound damping layer comprising a first mass layer, a first viscoelastic layer, a constraining layer having a first side and a second side, a second mass layer, and a second viscoelastic layer, wherein the first viscoelastic layer is positioned between the first side of the constraining layer and the first mass layer, and the second viscoelastic layer is positioned between the second side of the constraining layer and the second mass layer;
an acoustical absorption layer coupled to the sound damping layer, said acoustical absorption layer having a higher Sound Absorption Average (SAA) value than the sound damping layer;
and
a compressible material, which provides sound attenuation, provided along one surface of at least one edge of the ceiling panel assembly;
further wherein
said compressible material is in direct contact with at least one of said sound damping layer and said acoustical absorption layer.
