Abstract—The active noise cancellation (ANC), also known as “anti-noise” and “active noise control” involves the electro-acoustic generation (usually with loudspeaker) of a sound field to cancel an unwanted existing sound field. A typical single-channel active noise system consist of: a microphone reference sensor to sampled the disturbance to be cancelled, an electronic control system to process the reference signal and generate the control signal, a loudspeaker driven by the control signal to generate the cancelling disturbance, an error microphone to provide the controller with information so that it can adjust itself to minimize the resulting sound field. In this paper I will present a model of the above technology which can be used in industries in order to prevent noise pollution and provide safety to the workers working under excessive noise.
Index Terms—basic principle, control system design, feedback control, working and implementation of ANC
