...In Amiet’s work [9], the scattering equivalent sources are defined as if the airfoil were infinite in the upstream direction, but the radiation integral is calculated over the effective finite chord length....
[...]
...The problem of broadband trailing-edge noise modelling, as stated by Amiet [9], has been revisited by adding a leading-edge back-scattering correction and a 3D extension to the original formulation....
[...]
...This back-scattering correction has been developed here because the induced loads do concentrate at the leading edge, in the same way as found in classical linearized theories of unsteady aerodynamics [21] (the derivative leading to P2 generates a factor of ðX þ 2Þ )....

...When addressing scattering problems in aeroacoustics, Amiet applies this result to determine the disturbance wall pressure generated when an incident vortical velocity field impinges on the leading edge of an airfoil [21] or when an incident (aerodynamic) wall pressure field is convected past the trailing edge [9]....
