METHOD, SYSTEM AND COMPUTER PROGRAM FOR THE ACOUSTIC ANALYSIS OF A MACHINE

摘要

The invention relates to a method for the acoustic analysis of a machine (M), comprising the acquisition of at least one acoustic signal supplied by at least one microphone (7) positioned in the machine, characterised in that it comprises the following steps: separation of at least one acoustic signal into a plurality of sound sources, said signal being modelled as a mixture of components, each one corresponding to a sound source; for at least one separate sound source, determination of a characteristic acoustic signature; comparison of at least one characteristic acoustic signature with at least one reference acoustic signature recorded in a reference database (5).
