TABLE I.
Residual hearing status, DPT level, type of DPT modulation, and number of data records for the ten animals included in this study. Hearing status is assessed by the CAP threshold for a 100-μs click in the non-implanted ear. A click at 0 dB re: 1 V approximately corresponds to a 100 dB SPL peak sound pressure. When two thresholds are given, the first one was measured just after deafening, and the other one at the end of the experiment. DPT modulation is coded as follows: U is unmodulated, S is sinusoidal modulation, and V is vowel modulation.
