Three electrode-pairing methods give inconsistent results across individual implant users

Evidence

In general, clear monaural and binaural eABRs and BICs were obtained in most of the subjects. All but one subject showed nicely tuned pitch matching, IPTD sensitivity, and BIC as a function of electrode number. However, the pairing results were not always consistent across methods. The IPTD paring results of some subjects are spanned across several electrodes, which is consistent with the previous finds that ITD JNDs do not changed much until there is a 3–6 mm mismatch compared to the best matched place condition (van Hoesel and Clark 1997 ). Interaural pitch comparison shows some predictive value in selecting interaural electrode pairs, but it may not fully compensate for any underlying differences between the two implanted cochleae. In line with previous studies (van Hoesel and Clark 1997 ; Long et al. 2003 ; Poon et al. 2009 ) the pitch matched pair does not guarantee best IPTD sensitivity. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1471
