An active noise control filter arrangement with an adaptive filter structure, the arrangement comprising: a controllable filter module configured to process according to a controllable K×M filter matrix with K≥1 and M≥1,K input signals to provide M output signals, the K×M filter matrix having variable filter coefficients and being controlled by updating the filter coefficients; a filter control module configured to update the filter coefficients dependent on the K input signals and L≥ 1 error signals, the L error signals being representative of at least one performance criterion of the filter module; and an update control module configured to apply a leakage functionality and a convergence functionality to the updated filter coefficients, characterized in that: the leakage functionality is controlled by a spatial freeze functionality and a leakage threshold functionality; the convergence functionality is controlled by a freeze functionality and the spatial freeze functionality; the filter control module and the update control module are operated in the frequency domain; and in the frequency domain, the leakage functionality is applied to the updated filter coefficients by multiplying a leakage factor with the updated filter coefficients, and the convergence functionality is applied to the updated filter coefficients by subtracting a convergence value from the updated filter coefficients; the spatial freeze functionality is controlled by a spatial freeze control functionality, the spatial freeze control functionality being configured to change adaptation of the filter coefficients to temporary reduce the bandwidth of the leakage functionality and the convergence functionality if the updated filter coefficients are detected to be invalid due to a change of the characteristics of a secondary acoustic path; and the leakage threshold functionality comprises a ramp-up detection that is controlled by a leakage threshold functionality, the leakage threshold functionality being configured to detect whether the active noise control filter arrangement is in an adapting state or adapted state and to adjust the leakage functionality dependent on the detected state. a controllable filter module configured to process according to a controllable K×M filter matrix with K≥1 and M≥1,K input signals to provide M output signals, the K×M filter matrix having variable filter coefficients and being controlled by updating the filter coefficients;
