Over-frame blanket assemblies and methods of installation in fuselage assemblies

A fuselage assembly for an aircraft, the fuselage assembly comprising:

• a fuselage skin;
• a structural component;
• a cabin liner having an outer side facing the fuselage skin;
• an over-frame blanket assembly disposed between the fuselage skin and the cabin liner and separated from the cabin liner, the over-frame blanket assembly comprising a first blanket piece, the first blanket piece comprising:
• a first sound barrier layer that defines a first outer surface of the over-frame blanket assembly that is exposed radially inward of the over-frame blanket assembly and faces the cabin liner;
• and
• a first sound absorbing layer that defines a second outer surface of the over-frame blanket assembly facing the fuselage skin;
• and
• an acoustic barrier patch comprising a sound barrier that is adhered directly to the first sound barrier layer and is adhered directly to an outer portion of the structural component.

An over-frame blanket assembly for a fuselage assembly of an aircraft, the over-frame blanket assembly comprising:

• a first sound barrier layer that defines a first outer surface of the over-frame blanket assembly, wherein the first sound barrier layer is exposed outward of the first outer surface;
• and
• a first sound absorbing layer that defines a second outer surface of the over-frame blanket assembly, wherein the first sound absorbing layer is exposed outward of the second outer surface for facing a fuselage skin when installed in the fuselage assembly,
• wherein the first sound barrier layer and the first sound absorbing layer define an entire depth of the over-frame blanket assembly.
