1. An acoustic monitoring system comprising:
one or more acoustic sensors disposed on, within, or proximate one or more pieces of equipment, the one or more acoustic sensors configured to record sound; and
a server in communication with the one or more acoustic sensors, the server comprising memory and one or more processors configured, for each individual acoustic sensor of the one or more acoustic sensors, to:
monitor, using the acoustic sensor, sound generated by the component during subsequent operation of the one or more pieces of equipment to generate operational audio signature data;
compare the operational audio signature data to a stored baseline audio signature data;
determine that the operational audio signature data corresponds to an abnormal condition associated with the at least one component based on comparing the operational audio signature data to the stored baseline audio signature data; and
generate an alert indicative of the abnormal condition.
