This method is characterised by the steps consisting in: - measuring (16) the filtered amplitude of the detected activity (15), - adjusting (16) the detection threshold to a predetermined fraction of this measuring amplitude, - counting (17) an absolute refractory period following this detected activity, - counting (18, 19) a refractory noise period following this absolute refractory period, - restarting (21, 25, 19) this refractory noise period in the event of detected activity exceeding the detection threshold during the refractory noise period, and - incrementing (24) the detection threshold in the event of detection (21) in the refractory noise period, so as to increase the detection threshold above the amplitude of the noise. <IMAGE> |
