comprising methods for the design, optimization of the
technical design and / or operation of a
machine, aircraft or vehicle - Input (S1) of parameter values of the
machine, aircraft or vehicle by at least one
test subject on an end device, wherein the parameter values are design parameter values,
technical design parameter values and / or operational parameter values of the
machine, aircraft or vehicle, - Playback of audio signals (S2) on the terminal device, which reproduce the sound of the machine, aircraft or vehicle based on the entered parameter values, - Evaluating the auditory impression (S3) of the audio signals by the
test subject and obtaining a subjective
evaluation result from the
test subject, - Input (S4) of the subjective
evaluation result by the test subject on the terminal device, - Determining (S5) a relationship between the parameter values, or sets of parameter values, and the subjective
evaluation result, - Design (S6), optimization of the
technical design and / or operation of the machine, aircraft or vehicle, taking into account the relationship of the parameter values, or sets of parameter values, with the subjective evaluation result, wherein in the design, optimization of the technical design and / or operation parameter values are used which, in the operation of the machine, aircraft or vehicle, result in noises of the machine, aircraft or vehicle that correlate with a subjective evaluation result corresponding to a predetermined evaluation result, preferably a positive evaluation result.
