FIG. 3 illustrates an example display (e.g., a screen shot) 340 of alerts 342-1 through 342-10 (collectively referred to herein as alerts 342) and alert 344 of anomalous audio portions provided (e.g., displayed) to a user (e.g., technician) in accordance with an embodiment of the present disclosure. The display can be provided to the user by, for example, computing device 110 previously described in connection with FIG. 1.

As shown in FIG. 3, display 340 includes a graphical representation (e.g., timeline) of the magnitude of the audio sensed during the operation of equipment (e.g., an AHU) of an HVAC system of a facility throughout a particular day. As shown in FIG. 3, the graphical representation includes alerts 342 and 344 that each correspond to the occurrence of a different anomalous portion of the audio (e.g., to the time when each respective anomalous portion of the audio was sensed). For instance, alert 342-1 corresponds to an anomalous portion of the audio sensed around 6:45, alert 342-2 corresponds to an anomalous portion of the audio sensed around 8:30, etc.
