Normalized criterion speech bandwidth (CSB) as a function of age for individual child listeners between the ages of 6 and 14 years. Results for the low-frequency band are in the left panel, and results for the high-frequency band are in the right panel. The mean normalized CSB for adult listeners is plotted as a filled square on the right side of each panel, with error bars demarcating one standard deviation above and below this mean. The shaded region indicates ± 2 standard deviations around the adult mean. The dark line in each panel characterizes the relationship between bandwidth and child age, calculated using a least squared method; correlations between CSB and age are r=−0.74 and r=−0.78 for the low- and high-frequency bands, respectively.
