The present disclosure relates to an active acoustic control system comprising: a first sensor arrangement arranged to sense an acoustic signal in the region of an object, the acoustic signal having a scattered acoustic pressure component and a total acoustic pressure, the first sensor arrangement being arranged to sense the total acoustic pressure; and a processor configured to apply a first filter to filter the total acoustic pressure and provide a filtered output signal; and estimate the scattered acoustic pressure component based on the filtered output signal from the first filter.
