Abstract:
A method for determining the position of impacts on an object comprising two acoustic sensors, and N active areas of said object, comprises the steps of: (a) receiving two acoustic signals S1(t) and S2(t); (b) calculating a sample signature function SIGS(ω)=S1(ω)−S2(ω)*, where S1(ω) and S2(ω) are the respective Fourier transforms of S1(t) and S2(t), (c) comparing SIGS(ω) with N predetermined reference signature functions SIGR,(ω) corresponding to the predetermined area j for j from 1 to N; (d) determining the active area in which the impact occurred, on the basis of the comparison of step (c).
