Previous approaches for monitoring industrial equipment, such as, for instance, equipment of an HVAC system, may use vibration sensors to detect faults occurring in the equipment. However, in order to effectively detect faults, such vibration sensors need to be in direct contact with (e.g., attached and/or mounted to) the equipment, which results in additional downtime being needed for calibration and/or repair of the sensors. Accordingly, such vibration sensors may be considered invasive sensors relative to the HVAC system. Further, such vibration sensors may only be usable with certain types of HVAC equipment (e.g., such vibration sensors may be equipment specific). Accordingly, such vibration sensors may not be considered agnostic relative to the equipment of the HVAC system.

In contrast, embodiments of the present disclosure may use audio sensors to detect faults occurring in industrial (e.g., HVAC) equipment. Such audio sensors may not need to be in direct contact with the equipment to effectively detect faults in the equipment, and therefore may be considered non-invasive sensors relative to the HVAC system. Further, such audio sensors may be usable with all types of industrial equipment (e.g., may not be equipment specific), and therefore may be considered agnostic relative to the equipment. Further, such audio sensors may be cheaper and/or easier to install than vibration sensors.
