Abstract
An acoustic absorption trim panel includes a composite core, a decoupler layer, and a mass barrier layer. By ensuring that the mass barrier layer remains limp in a limp area but in contact with the composite core through the decoupling layer, damping greater than that imparted in conventional construction is achieved.
