Overview

This study shows the influences of structural-acoustic coupling and viscoelastic properties on sound transmission loss, indicating new potential for noise control applications.

Key Points

  • Sound transmission loss is significantly impacted by core thickness and structural stiffness.
  • Numerical solutions reveal that larger radii may reduce sound transmission loss performance.
  • Viscoelastic damping and gradient index significantly affect low-frequency sound transmission loss.
  • Resonance frequencies remain consistent despite changes in aerodynamic conditions.
