A mock-up of an airplane cabin can be a good simulation tool for the study, prediction, demonstration, and jury testing of interior aircraft sound quality. The authors used real flight recordings created with vibrational and microphone transducer arrays in combination with multichannel equalization with least-mean-square optimization techniques. The paper presents physical evaluations of reproduced sound fields on the basis of real flight recordings using an 80-channel microphone array and 41 reproduction sources in the cabin mock-up. To provide a faithfully reproduced sound environment, time, frequency, and spatial characteristics should be preserved. Results are satisfactory given the various limitations and constraints.
