Abstract (en)
[origin: WO02091354A1] The invention relates to a method and device for automatically differentiating and/or detecting acoustic signals, whereby these are statistically analyzed at least in part and their reflection coefficients of at least one order are calculated. The invention is characterized in that a comparison value, which is dependent exclusively on a single reflection coefficient, is calculated and this comparison value is compared with at least one predetermined reference value.
