The human factors engineering, and noise and vibration designs are in great demands in the large passenger aircraft cabin in China. To overcome the technical bottleneck of the comfort evaluation of aircraft cabin noise and vibration, we will study the mechanism and model of coupling effects of noise and vibration on the comfort of large passenger aircraft cabins. Field measurements will obtain the noise and vibration data of typical operating conditions, cabins and sections of large passenger aircraft. The time-frequency characteristics of the data will be analyzed, and the synthetic method of virtual samples will be studied by considering the aspects of auditory hearing and vibration perception. A subjective evaluation experimental technique for noise and vibration in large passenger aircraft cabins will be developed by using the sample synthesis method and the elegant and unified metric method. The effects of noise and vibration on the comfort of large passenger aircraft cabins will be studied through subjective evaluation experiments. The mechanism of coupling effects of noise and vibration on comfort will be revealed. Finally, we will establish the total discomfort model of combined noise and vibration for the large passenger aircraft cabins from the subjective and objective integration. We will also analyze the accuracy, robustness, and applicability of the model through the verification experiment. The research will provide theoretical and technical support for the design of noise and vibration control in the cabin of large passenger aircraft in China, and formulate regulations of noise and vibration comfort in airworthiness standards.
