Embodiment Construction

[0121] figure 1 An aircraft 10 is shown, which has a fuselage 12 and two wings 14 attached laterally to the fuselage, on which engines 15 are arranged. fuselage 12 in figure 1 It is shown in section transverse to its longitudinal axis. The fuselage 12 is divided by a horizontally extending floor 20 into an upper passenger cabin area 16 and a cargo area 18 arranged below the upper passenger cabin area. Furthermore, the fuselage 12 has a substantially surrounding outer aircraft skin 22 which is fastened to an aircraft fuselage structure (not shown in detail). In simple terms, the aircraft fuselage structure consists of a support structure consisting of bulkheads and stringers and ensures a stable design for absorbing external and internal loads.

[0122] In the cabin area 16 arranged above the floor 20 there are lateral cabin linings 24 , 26 along the outer wall 22 and a roof cabin lining 28 in the roof area.

[0123] The elements of the cabin lining 24 , 26 , 28 together wi...

Abstract

The invention relates to an aircraft cabin panel (40) for sound attenuation in an interior space, which has, in at least one region, a sandwich structure with a core layer (50), a first covering layer (52) and a second cover layer (54). The core layer consists of a sound-absorbing open-cell core material. The first and second cover layers are connected planarly to the core layer. The first covering layer is arranged in a direction of sound waves to be absorbed, and the second covering layer is arranged opposite to the first covering layer. The first covering layer is designed to be sound-permeable.

Description

technical field [0001] The invention relates to an aircraft cabin panel for sound attenuation in an interior space. The invention also relates in particular to an aircraft having an interior space lining with sound-absorbing and sound-insulating panels. Background technique [0002] In aircraft, sound-damping panels are used in the region of the cockpit in order to improve the acoustics of the interior of the cockpit by reducing disturbing sounds with the help of the panels. In general, as the requirements for spatial comfort increase, so do the requirements for the quality of the dwelling in the aircraft, since in addition high requirements are also placed on the acoustics of the room during flight operations. For this purpose, it is desirable to use wall panels for sound absorption in the interior of, for example, an aircraft cabin, in order to minimize the noise load inside the cabin. The noise to be reduced is, for example, the noise generated by the engine, the noise ...
