Abstract

This paper proposes a preliminary theoretical study for sound field and sound environment reproduction in

flight vehicles. A fully-coupled cavity, cylindrical shell and exterior radiation model approximates an aircraft

cabin mock-up. Material and geometry charateristics are inspired by measurements perfomed on a cabin

mock-up. The sound field reproduction is based on reproduction error minimization at a microphone array

positionned in the cavity. Two reproduction systems, based on actuators or loudspeakers are simulated in

order to compare their feasability and performance. The model linking excitator strength with the sound

pressure on the spatially extended array region is developped in a matricial form. The promising results

obtained in terms of reproduced pressure in the array region in both cases presume the reliability of such

dedicated systems.
