Contributions of better-ear SNR (dark green shaded area) and BMLD (light green shaded area) to the overall predicted binaural benefit of the DynBU_fast approach (the sum of both contributions, indicated with black squares). The overall prediction is plotted as detection benefit for the different experimental conditions of Figure 7 derived as the difference between masker level (60 dB SPL) and predicted detection thresholds in dB SPL of the target harmonic complex tone. The left column (panels a, c and e) shows data for α = 0.1 and the right column (panels b, d and f) for α = 0.5.
