AB  - This presents a systematic investigation into the localization accuracy of two First Order Ambisonics (FOA) decoding methods for head-static binaural reproduction: the magnitude least squared method used in the IEM Binaural Decoder and the basic decoding method for the cube virtual loudspeaker layout. The two decoding methods were compared against a directly binauralized reference for five vertical positions (-45° to 45° at 22.5° intervals) for eight horizontal positions (0° to 315° at 45° intervals). A train of pink noise bursts were used as stimuli. Results indicate that little elevation was perceived across the tested azimuths for all three reproduction methods. The lack of elevation has implications for FOA microphone placement in terms of microphone height.
