%VICENTE2020_BETTEREARSNRFRAME calculates the better ear SNR
%   Usage: [weighted_BE_Aud_SNR, BESNR_perFB] = vicente2020_betterearsnrframe(fs, fc, MaskerSig, targ_left,targ_right, InternalNoise_L, InternalNoise_R, ceiling, weightings)
%
%   VICENTE2020_BETTEREARSNRFRAME computes the better ear SNR
%   in all frequency bands centered at fc, considering the audiogram.
