Highlights from research

On the left is the schematic of a numerical setup for optimal pressure wave control using monopole sources (shown in red) for a spherical target domain (shown in green). On the right, the simulation result of the optimal pressure wave control calculated by an iterative LMS solver on the x-y plane. The amplitude of the complex sound pressure is plotted in colour for the primary field before iteration I=0 (left) and after iteration I=100 (right). The position of the monopole sources on the x-y plane is marked in black. The noise source was modelled as a monopole source in the negative x direction of the sphere volume, the frequency shown is 150Hz.
