Masking functions showing total masking as a function of the number of masker components for each of the eight adult listeners in this study. Total masking is defined as the dB difference between the target threshold (75% correct in 2AFC) in quiet and in the presence of a masker. The horizontal lines represent total masking with a broadband noise masker. Solid symbols connected by solid lines (and the solid horizontal line) refer to masking with the ipsilateral masker. The open symbols connected by dashed lines (and the horizontal dashed line) refer to masking with the contralateral masker. The error bars around each data point represent the 95% confidence intervals determined by the bootstrapping technique described in the text. Each panel is labeled with the 3-letter listener code and the listener’s age, given in decimal years. Note that the data from the ipsilateral condition are a reanalyzed version of the data shown in Oh et al. (2001).
