Abstract

The noise radiation of the panels with different treatments under a turbulent boundary layer (TBL) excitation is tested in an anechoic wind tunnel. The averaged dimensionless spectrum for the response and the radiated sound power of panels with different size, stiffening and damping treatments are collected at the condition of various flow speeds. Numerical analysis of panel parametric sensitivity on the radiated noise due to TBL excitation is also presented for a comparison.
