Abstract
In a method for active interference noise suppression according to the invention, a transfer function of a secondary path between a loudspeaker and an error microphone is measured (20). A transfer function of the primary path between the reference microphone and the error microphone is estimated (21) based on the measured transfer function of the secondary path. Then, filter coefficients for generating filtering of the cancellation signal are determined (22) based on the estimated transfer function of the primary path.
