A multi-disciplinary process to numerically predict the cabin noise in the the early aircraft design stage is proposed. This starts at conceptual level and entails disciplines like loads, structure and cabin design as well as noise prediction. Utilizing CPACS to ensure consistency among the different disciplines, interior noise for aircraft concepts using different energy carriers is compared.
