1. A device comprising:
at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to:
receive at least a first acoustic signal from a source of sound, the first acoustic signal comprising a sonic code generated by the source of sound identifying the source of sound;
determine at least an azimuthal direction to the source of sound from an origin based at least in part on the first acoustic signal; and
transmit at least a first range-finding beam based on the azimuthal direction determined based at least in part on the first acoustic signal.
