Recovered envelope cues in neural responses are predicted to decrease as the number of chimaeric analysis bands increases. Spike trains were obtained from one model AN-fiber (CF = 550 Hz). Same stimuli were used as in Figure 7. Squares: chimaeras with fine structure from speech and envelope from a spectrally matched noise. Triangles: chimaera with speech envelope and noise fine structure. Dashed lines at ρ = 0.1 represent the estimated noise floor for uncorrelated conditions (see Fig. 3). Overall speech level was 35 dB SPL.
