Active control of turbulent boundary layer-induced sound transmission through the cavity-backed double panels

This paper presents a theoretical study of active control of turbulent boundary layer TBL induced sound transmission through the cavity-backed double panels. The aerodynamic model used is based on the Corcos wall pressure distribution. The structural-acoustic model encompasses a source panel (skin p...
