Definitions

  • the present invention finds an advantageous application in assisting in the detection of failures of industrial machines or of engines, in particular by obtaining sound recording sequences of acceleration and deceleration phases of the engine speed.
  • the application of the method within the meaning of the invention makes it possible to isolate a sound sub-sequence corresponding for example to a full speed or to an acceleration phase, this sub-sequence being, if necessary, compared to a sub- reference sequence.
  • the segments s ⁇ (t) and ⁇ j (t) are first formed by cutting the audio signal using a time window h L (t), of width L and defined ( of non-zero value) between 0 and L.
  • This window can be of rectangular type, of so-called “hanning” type, of so-called “level hanning” type, or other.
  • a preferred type of time window is obtained by concatenating a rising edge, a landing and a falling edge. The preferred time width of this window is shown below.
