A contribution vibroacoustic psychoacoustic design Project Details
| Abstract |
This research framework looks at how to combine vibro‑acoustic and psycho‑acoustic design methods for lightweight composite sandwich structures. Traditional optimization of sandwich panels usually tries to make them as light as possible while keeping them stiff. That approach often creates unwanted noise and vibration. Typical mitigation techniques measure only physical vibro‑acoustic quantities—such as transmission loss or radiation efficiency—and ignore how people actually hear the sound. To fix this gap, the project proposes an optimization method that links structural dynamics with psycho‑acoustic metrics like loudness, sharpness, and fluctuation strength. By changing the geometry and material properties of the sandwich core and the face sheets, the design space is explored to reduce
both the amount of sound radiated and the discomfort felt by occupants. Finite element analysis and boundary element methods are used to model the structural‑acoustic response. The resulting acoustic pressure fields are then run through psycho‑acoustic algorithms to assess sound quality. The outcome is a complete framework for designing next‑generation aerospace panels that balance structural efficiency with better cabin acoustic comfort.
