Assessing Noise Generation Combining Multiple Physics: DAVA Approach
Overview
Aero-Vibro Acoustics is a multidisciplinary field that combines principles from aerodynamics, structural dynamics, and acoustics to study the generation, propagation, and control of noise and vibrations in aerospace and mechanical systems. It is applicable in aerospace, automotive, and industrial settings where reducing noise and controlling vibrations are critical for performance and comfort. The Decoupled Aero-Vibro-Acoustic (DAVA) approach integrates aerodynamic excitation, structural response, and acoustic radiation into a single simulation workflow to accurately predict airborne and structure-borne noise.
