Abstract: An n-phonic energy detection (“NED”) system includes two antenna structures separated by a distance and configured to be placed adjacent one of a pair of human ears. Each of the two antenna structures includes antenna elements. The NED system also includes speakers configured to be placed adjacent one of the pair of human ears. The NED system also includes radio frequency (“RF”) detectors configured to detect RF energy emitted from a source and received by the two antenna structures, and an amplifier that amplifies signals from the RF detectors and outputs the amplified signals to a computer and to the speakers corresponding to the antenna structure to be placed adjacent the same one of the pair of human ears.
