Predicted binaural release from masking (BRM, shown on the y-axis) defined as the difference between SRTs of the first condition of experiment I (D₀N₀) and the first condition of experiment III (D_πN₀) using bBSIM-SII (black line), STI_NCV (light gray line), and NI-STOI (dark gray line). The back-end reference values are shown on the x-axis. The red line shows the measured BRM of 7.8 dB. The yellow circles show the optimal references, which allows predicting accurately the measured BRM for the SII and the STI_NCV (see Fig. S3). For the NI-STOI the optimal reference allows predicting the measured BRM with less overestimation (see Fig. S3).
