System and method for detecting issues in a turbomachine by monitoring noise generated by the turbomachine

A system for detecting issues in a turbomachine when the turbomachine operates by monitoring noise generated by the turbomachine, wherein the system comprises:

• at least one microphone positioned in an area where the turbomachine is installed and operates, the at least one microphone being configured to capture noise generated by the turbomachine and propagated through ambient air,
• an input interface electrically coupled to the least one microphone, the input interface being configured to receive signals generated by the at least one microphone,
• an output interface configured to signal issues in the turbomachine once detected, and
• an electronic processing unit electrically coupled to the input interface and the output interface, the electronic processing unit being configured to receive input signals from the input interface, to process the received input signals, to generate output signals based on the received input signals, and to transmit the generated output signals to the output interface, the output signals being related to detected issues in the turbomachine;
• wherein the electronic processing unit is configured so that when processing the received input signals:
• a) to determine a sound power value from a received input signal,
• b) to compare the determined sound power at least with a first power value, and
• c) to determine an output value of an output signal, the output value being related to the difference between the determined sound power and at least the first power value;
• wherein the processing of the received input signals by the electronic processing unit is performed through a set of algorithms concurrently, the algorithms of said set being of different
