1. A device for detecting percussion events comprising: at least one axial accelerometer sensor, at least one axial magnetometer sensor insensitive to translational vibrations, low cut-off filtering means provided with at least one input receiving measurements transmitted by the at least one axial accelerometer sensor and the at least one magnetometer sensor, and analysis means for analyzing the accelerometer and magnetometer measurements filtered by said low cut-off filtering means, the analysis means comprising comparison means for comparing data from the filtered accelerometer measurements with at least one threshold, thereby determining a first outcome relating to the accelerometer measurements, and for comparing data from the filtered magnetometer measurements with at least one threshold, thereby determining a second outcome relating to the magnetometer measurements; and the analysis means further configured to detect a percussion event based on the first outcome and the second outcome so that a rotational acceleration not filtered by said low cut-off filtering means is not detected as a percussion event.
