Psychometric functions for speech-noise mixtures processed with TF masks. Each line represents a single listener, identified by the same symbol in each panel. The horizontal line marks the value of the Recognition Score, 0.5, that defined the SRT. The abscissa scale changes in each panel but the difference between the lowest and highest values is a constant 18 dB. (A) Intelligibility for sentences in talker-specific noise, prior to application of TF masks. (B) Intelligibility for TF masks generated with LC = 0 dB. (C) Same as (A), for TF masks generated with LC = −8 dB. (D) Same as (A), for TF masks generated with LC = −16 dB. (E) Same as (A), for TF masks generated with LC = −24 dB.
