1. A method, comprising:
determining, by an unmanned vehicle comprising a processor, whether an acoustic signal satisfies a signal criterion; and
in response to determining that the acoustic signal satisfies the signal criterion, initiating, by the unmanned vehicle, autonomous navigation of the unmanned vehicle, wherein the signal criterion comprises a standby criterion that defines whether the autonomous navigation of the unmanned vehicle is to be in a standby mode, and wherein being in the standby mode comprises staying, by the unmanned vehicle, at a defined location specified for being in the standby mode.
