Plasma based noise reduction system

An active noise reduction system comprising an electroacoustic plasma transducer for mounting in an installation structure and an acoustic sensing system, the electroacoustic plasma transducer comprising a plasma electrode arrangement including a collector electrode and a corona electrode, and a control system connected to the plasma electrode arrangement for supplying power to the plasma electrode arrangement, the control system comprising a controller, and a amplification circuit, the acoustic sensing system connected to the control system providing a measurement signal of an environmental sound to control the output of the electroacoustic transducer for reducing noise, wherein the control system comprises a filter implementing a control transfer function θ(s) based on a model of the electroacoustic plasma transducer, said filter implementing said control transfer function θ(s) being further based on a frequency-dependent target acoustic impedance Ztg(ω).
