‘Tech’ is the Technology Rating Scale for the CI processor: 1 = MSP, 2 = Spectra, 3 = Esprit 22, 4 = Esprit 3G, and 5 = Freedom. ‘T’ and ‘C’ map levels are given in nanocoulombs (nC). Speech scores are percent-correct word scores. At Session 1, speech tests are the Lexical Neighborhood Test presented at 70 dB SPL (LNT70) and the BKB sentences presented in quiet (BKBQ). At Session 2, approximately 8 years later, two additional speech tests were employed, the Lexical Neighborhood Test presented at 50 dB SPL (LNT50) and the BKB sentences presented with a +10 dB signal-to-noise ratio (BKBN). Note: Subjects 96103 and 96105 did not complete the LNT70 test at Session 1.
