DESIGN AND DEVELOPMENT OF THE VISUAL AND AUDITORY LAYER FOR DIFFERENT CABIN/COCKPIT LAYOUT

This study, part of the Italian PRIN project TWINCRAFT - Digital Twin for Human-Centred Design of Future Aircraft, explores the enhancement of acoustic comfort for passengers and pilots through noise reduction in aircraft using advanced acoustic metamaterials. We assess comfort via a human-centered design approach, integrating noise auralization in eXtended Reality (XR) within the passenger cabin. This novel method utilizes augmented and virtual reality technologies alongside physical flight simulators to evaluate the efficacy of noise reduction strategies. The acoustic field, i.e., noise, calculated using accurate numerical analyses, is integrated into a digital mock-up of an aircraft through auralization. In this way, by combining the auditory layer and visual layer defined in previous works, it is possible to create an immersive experience for the user. The paper details the auralization process, from vibro-acoustic analysis of a section of an aircraft fuselage to the creation of an acoustic digital twin, thereby optimizing the aircraft design process.
