1. Method for determining the location of an impact on a surface of an object based on the analysis of an acoustic signal generated by the impact comprising:
- a signal treatment step of weighting the acoustic signal to thereby take into account spurious contributions in particular due to reflections at the border of the object,wherein the signal treatment step of weighting comprises a step of identifying a first wave front of the acoustic signal and a step of applying a damping window,wherein the step of applying a damping window comprises using multiplying the acoustic signal with an exponential damping window;
