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 S(t) and S(t); (b) calculating a sample signature function SIG(ω)=S(ω)−S(ω)*, where S(ω) and S(ω) are the respective Fourier transforms of S(t) and(t), (c) comparing SIG(ω) with N predetermined reference signature functions SIG(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).
