Colloquium: Petre Calin Nae (ASM)

The aviation industry aims to enhance passenger comfort and safety by reducing noise in aircraft cabins. Traditional soundproofing methods conflict with the goal of lightweight, fuel-efficient aircraft. This thesis explores using Helmholtz resonator-based metamaterials in lightweight composite acoustic panels. Findings show that face sheet lay-up and non-resonant volumes significantly impact sound absorption and resonator interference. The study concludes that incorporating these metamaterials can achieve effective, lightweight acoustic panels for aircraft cabins and proposes a design concept.
