1. A method of acoustic communication of information, comprising;

  • sensing a stimulus via one or more sensors;

    generating a sensor output signal based on the sensed stimulus;

    selecting a frequency channel from among a plurality of frequency channels based on upon a time interval;

    encoding an acoustic communications signal onto the selected frequency channel based on information from the sensor output signal by varying a length of time delay in a transmission between adjacent frequency channels; and

    acoustically transmitting the encoded acoustic communications signal.
