Acoustics based anomaly detection in machine rooms

A computer system for monitoring a plurality of machines located in an operating environment, the computer system comprising:

• one or more computer processors, one or more computer-readable storage media, and program instructions stored on one or more of the computer-readable storage media for execution by at least one of the one or more processors, the program instructions, when executed by the at least one of the one or more processors, causing the computer system to perform a method comprising:
• receiving, from a sensing device over a network to a computing system, a first acoustic signal readings and their respective detecting locations;
• generating, by the computing system, a first acoustic signal spatialization map containing characteristic data signatures, based on the first acoustic signal readings and their respective detecting locations, each of the characteristic data signatures being associated with one or more of the plurality of machines;
• receiving, from the sensing device over the network to the computing system, a second acoustic signal readings and their respective detecting locations;
• generating, by the computing system, a second acoustic signal spatialization map containing characteristic data signatures, based on the second acoustic signal readings and their respective detecting locations, each of the characteristic data signatures being associated with one or more of the plurality of machines;
• determining, by the computing system, that there are one or more differences, that exceed a predetermined threshold value, between one or more characteristic data signatures in the first acoustic signal spatialization map and corresponding one or more characteristic data signatures in the second acoustic signal spatialization map;
• identifying at least one of the plurality of machines that are associated with the determined differences;
• identifying, by the computing system, a corrective action to perform on a machine of the plurality of machines, based on the determined one or more differences in the generated first and second acoustic signal spatialization maps;
• and
• transmitting, by the computing system to a corrective action module in the operating environment, commands to cause the corrective action module to perform the identified corrective action.
