Panel A: Group mean scores on the CNC monosyllabic words test (60 dB SPL), HINT sentence test in quiet (60 dB SPL), HINT sentence test in noise (60 dB SPL +8), and the Adaptive HINT test are shown for adult cochlear implant subjects when listening with HR (gray bars) and HR 120 (black bars) at four test intervals. Panel B: Group mean scores on the HINT at 50 dB SPL, TIMIT at 60 dB SPL, and BKB-SIN (65 dB SPL) are shown for subjects when listening with HR (gray bars) and HR 120 (black bars) at three test intervals. In both panels, error bars represent +/− 1 SE from the mean.
