Abstract: A system includes an acoustic monitoring, analysis, and diagnostic system having a processor. The processor is configured to receive NF noise signals from a near field (NF) microphone array, the NF microphone array measures noises from a power generation system in a NF. The processor is configured to receive FF noise signals from a far field (FF) microphone array, the FF microphone array measures noises from a power generation system in a FF. The processor is configured to derive NF and FF noise measurements based on the signals and to synchronize the NF and FF noise measurements to create synchronized NF and FF noise data. The processor is configured to analyze the synchronized NF and FF noise data to create a NF and an FF noise signature. The processor is configured to diagnose root causes of noises generated from the power generation system and to report the root causes.
