Vibro-acoustics modeling of lightweight structures with attached noise control materials

Over the last two decades, the author's team has extensively investigated the modeling, characterization, and development of lightweight structures and their integrated sound packages, with particular emphasis on aircraft and aerospace applications. This keynote talk presents a comprehensive review of this body of research. Specifically, the presentation will demonstrate the remarkable effectiveness of the transfer matrix method, together with its numerous extensions, in accurately predicting the vibroacoustic response across a diverse range of lightweight structures and noise control materials. The impressive predictive capability of this methodology, particularly notable given its computational efficiency, will be illustrated through various excitation scenarios and systems featuring strategically positioned structured elements either within the structure or inside the attached noise control treatments.
