AUTOMATED DIAGNOSIS OF AUGMENTED ACOUSTIC MEASUREMENT IN INDUSTRIAL ENVIRONMENTS
A computer-readable medium may include instructions that may cause a processor to perform operations that may include receiving audio data representative of sound waves generated by industrial devices and extracting features from the audio data.
