Fig. 6.
Noise-induced changes in derived-band latency relative to the quiet condition. Panels a and b show the transition and steady-state portions, respectively. The coloured symbols show the average latency changes across participants as a function of derived frequency band. The error bars show the 95% CIs. The parameter is the noise level (pink: 20-dB SNR; red: 10-dB SNR). The grey lines and symbols show the maximal within-band latency changes that could theoretically arise within each frequency band, estimated using the travelling-wave delay measurements by Strelcyk et al. (2009). The rectangular coloured areas labelled ‘BB20’ and ‘BB10’ show the 95% CIs of the noise-induced changes in broadband response latency for each noise level. Latency shifts could not be assessed and are thus not shown for conditions where the response peaks did not reliably exceed the noise floor across participants
