A method for determining specifically relevant acoustic features of acoustic signals for the analysis of unknown sound signals a sound generation

摘要

A method for detecting acoustic features of acoustic signals which the presence or absence of a property of the acoustic signal or sound generator, characterized by the separate machining of two groups of acoustic signals in at least the steps of:1.) Detection of the sound signals and transfer into a computer readable audio - files, or transfer of a previously taken sound signal in the form of an audio file;2.) Generating a frequency spectrum of each sound signal;3.) Generation of predictors on the basis of the spectra of the two groups on the basis of the energy components in the selected frequency bands, wherein in each case takes place fora) the total - spectra and / orb) the tonal proportions of the spectra,4.) Generation of predictors derived by product formation and relations formation from the predictors;5.) Determination of the for the property of the sounder relevant acoustic features by logistic regression between the two groups with at least one of the under steps 4 and 5 and predictors produced with recovery of predictors derived from regression coefficient for individual predictors and..
