Abstract: The experimental evaluation of the acoustic environment during the flight of a spacecraft is very expensive. Thus, it is of great significance for the subsequent noise reduction and sound quality research to build a cabin mock-up on the ground to reproduce the acoustic environment based on the method of the sound field reproduction. In this paper, a sound field reproduction system using a multichannel least-square equalization method with a feedback control is proposed to reproduce the acoustic environment in a cabin mock-up. The targeted sound spectra at ten points are reproduced by eight loudspeakers. The errors of the total sound pressure level and the 1/3 octave spectrum level are within 1 dB and 3 dB, respectively.
