function [Loudness, LoudnessLeft, LoudnessRight] = moore2016_binauralloudness( SpecificLoudnessLeftMon, SpecificLoudnessRightMon )
%MOORE2016_BINAURALLOUDNESS Calculate the binaural loudness out of monaural loudness at 0.25-ERB steps
%
%   Input parameters:
%     SpecificLoudnessLeftMon : monaural specific loudness left ear
%     SpecificLoudnessRightMon : monaural specific loudness right ear
%
%   Output parameters:
%     Loudness      : binaural loudness
%     LoudnessLeft  : loudness at left ear
%     LoudnessRight : loudness at right ear
%
%   This code weights the respective monaural loudness taking account binaural
%   inhibition for calculating the binaural loudness in moore2016
%   in the version for TVL 2016 based on ANSI S3.4-2007 and Moore & Glasberg (2007).
