1. An audio signaling system for an automated machine, comprising:
a field audio system, comprising
a control hub including a user interface, and
an audio output device connected to the control hub, wherein the audio output device emits an audio action signal when an action instruction signal is sent from the control hub;
an audio control system onboard the automated machine, comprising
an audio input device, wherein the audio input device captures audio including the audio action signal when it is emitted by the audio output device,
a control circuit connected to the audio input device, wherein the control circuit includes a memory connected to a processor,
wherein the control circuit is connected to an automation system for the automated machine,
wherein the control circuit evaluates the audio from the audio input device to determine if current audio includes the audio action signal, and when the current audio is determined to include the audio action signal, the control circuit sends corresponding action instructions to the automation system; and
wherein during operation, the field audio system's control hub sends the action instruction signal to the audio output device when a user input is received through the user interface.
