Abstract: The invention relates to a method of detecting and locating noise sources each emitting respective signals Sj with j=1 to M, detection being provided by means of sound wave or vibration sensors each delivering a respective time-varying electrical signal si with i in the range 1 to N. According to the invention, the method consists: in taking the time-varying electrical signals delivered by the sensors, each signal si(t) delivered by a sensor being the sum of the signals Sj emitted by the noise sources; in amplifying and filtering the time-varying electrical signals as taken; in digitizing the electrical signals; in calculating a functional; and in minimizing the functional relative to the vectors nj for j=1 to M so as to determine the directions vector nj of the noise sources.

Abstract: According to the invention, the method of detecting and locating sources of noise each emitting respective signals Sj with j=1 to M, detection being performed using sensors each delivering a respective time-varying electrical signal si with i varying from 1 to N, consists in taking the time-varying electrical signals delivered by the sensors, each signal si(t) delivered by a sensor being the sum of the signals Sj emitted by the noise sources, in amplifying and filtering the time-varying electrical signals as taken, in digitizing the electrical signals, in calculating the functional f ( n 1 , … , n j , … , n N ) = ∑ k ≠ 1 R k1 with coefficients Rkl being a function of the vectors nj giving the directions of the noise sources, and in minimizing the functional f in such a manner as to determine the directions nj of the noise sources.
