All values are in percent-correct except age (in years) and HFPTA (in dB HL). See text for a description of spatial conditions (F-F and F-RF). Voice refers to performance on the voice discrimination task.
HFPTA, average of better-ear pure-tone thresholds at 2, 3, 4, and 6 kHz; MTT, male two-talker masker; FTT, female two-talker masker; SEM, single-channel envelope-modulated noise; SSN, steady-state speech-shaped noise.
