      The impedance boundary condition (IBC) lies in between a traditional reflective boundary condition and a fully non-reflective boundary condition. There is no direct implementation of an impedance based wall boundary condition. However one. The soft walls where the acoustics wave are partially dampened /partially reflected are then modeled as velocity inlet with velocity equal to zero. On this inlet one can then use the impedance boundary. Keywords: Acoustic, Impedance, Wall, BC, Boundary,
