Abstract

The nonlinear inverse problem of active sound control in a two-dimensional waveguide is addressed. To solve the problem, a numerical algorithm based on an exhaustive search for coordinates of the desired sources over a curvilinear mesh and on the regularized quadratic algorithm for minimization with respect to their intensities is proposed. Numerical results for circular and elliptical antenna arrays are discussed.
