Abstract:
1. Apparatus for carrying out a laboratory testing of an enclosed partial cabin to be installed as a resting cabin in a commercial aircraft, for an acoustic design and testing, characterized in that the partial cabin ( 1 ) is arranged via at least one vibration generator ( 4 ) for the simulation of an excitation structure-borne noise in an area of connection elements ( 2 ) to be connected to a fuselage structure of the aircraft, and elements ( 5 ) for an airborne noise excitation are allocated to the partial cabin ( 1 ), whereby the at least one vibration generator ( 4 ) for the structure-borne noise and the elements ( 5 ) for the airborne noise excitation are adjustable via control and regulating devices ( 6 ), based on signals that are generatable via a computer unit ( 7 ) with an input data file ( 8 ) of knowledge-based data, as well as, if applicable, by extrapolation of acoustic values at an installation location of the partial cabin in the commercial aircraft and of the design of the partial cabin ( 1 ).
