1. A method comprising:

  • under control of one or more computing devices configured with executable instructions,emitting, by an audio canceling device, information indicating a location of the audio canceling device;

    responsive to the emitted information indicating the location of the audio canceling device, receiving, at the audio canceling device, monitoring information indicating that an unmanned aerial vehicle (“

    UAV”

    ) will be within a defined distance of the audio canceling device, the monitoring information including a UAV audio signature representative of audio generated by the UAV;

    recording an audio signal from an environment in which the audio canceling device is located;

    processing the audio signal to determine a portion of the audio signal that corresponds to the UAV audio signature;

    determining, based at least in part on the audio signal, that the UAV is approaching the location of the audio canceling device;

    outputting from an output of the audio canceling device an audible notification that the UAV is approaching;

    generating an attenuation-signal based at least in part on the portion of the audio signal, wherein the attenuation-signal is generated by at least phase shifting the audio signal; and

    outputting the attenuation-signal from the output of the audio canceling device so that the portion of the audio signal is attenuated by the attenuation-signal within at least a portion of the environment;

    wherein the audible notification that the UAV is approaching that is output from the audio canceling device is distinct from the attenuation-signal based at least in part on the portion of the audio signal that is output from the audio canceling device.
