Abstract

A method, computer program product, and a computer system are provided for acoustic monitoring and fault reporting. A computer identifies a sound from a consumer device. Responsive to identifying the sound from a consumer device, the computer converts the sound to an acoustic signal. Responsive to converting the sound to an acoustic signal, the computer generates a current acoustic fingerprint from the acoustic signal. Responsive to generating the acoustic fingerprint, the computer identifies whether the current acoustic fingerprint contains an ideal acoustic fingerprint. Responsive to identifying that the current acoustic fingerprint does not contain the ideal acoustic fingerprint, the computer provides notification that the current acoustic fingerprint does not contain the ideal acoustic fingerprint.
