Figure 4:

Head-shadow benefit as a function of filter-cutoff frequency. The curved lines are sigmoidal fits of the data for each group/condition. Points in each panel represent the average SRT and error bars represent ±1 standard deviation. The vertical lines represent mean exclusion cutoffs for each group/condition. BI = bilateral; CI = cochlear implant; SSD = single-sided deafness; V-HR = high-resolution vocoder; V-LR = low-resolution vocoder.
