[weighted_BE_Aud_SNR, BESNR_perFB] = vicente2020_betterearsnrframe(fs, fc, MaskerSig, targ_left,targ_right, InternalNoise_L, InternalNoise_R, ceiling, weightings)
compute IN ALL frequency bandS centered at fc, the BE SNR, after considering audiogramme, applying ceiling. int_in is ear signals (in a time-frame) t_left/right are (longterm) power of the target at that ear in this band, t_phase is its corresponding interaural phase fs=sampling frequency
