Abstract:
Active noise control in a waveguide by applying an array of receivers and emitters placed on the inside waveguide wall is studied. The field of an emitter located inside the waveguide is measured and used to determine the amplitudes and phases of auxiliary emitters, whose field is applied to suppress the incident field.
Key words:active sound control, auxiliary emitter, receiver, array antenna, potential for Helmholtz’s equation, inverse problem, numerical solution of a system of algebraic equations.
