Beschreibung
Zusammenfassung:	A noise reducing device for an aircraft turbine engine, the device having a structure in the form of a stack of layers, such that a first and a second skin made of composite material form a first and a second outer layer, these outer layers being substantially parallel to one another and enclosing a central layer. The central layer has a honeycomb structure having partitions extending transversely from the first outer layer to the second outer layer so as to form cavities. The partitions are made of viscoelastic material and form an acute angle of inclination (α) with the first and second outer layers.
