Comparison of the Objective Measures and Behavioral Responses in Cochlear Implant Users Implanted with CI422: A Preliminary Study

Abstract

Objectives: The aim of the present study is to investigate the relationship between the eSRT and eCAP thresholds with the behavioral comfortable levels in CI users implanted with CI422. Materials and Methods: There were 10 CI user included in the study with mean age at evaluation 20.47. five electrodes were selected from different regions of cochlea for comparison. For these five electrodes, behavioral C levels were determined with Custom Soundâ 5.2 Fitting Software and eCAP and eSRT thresholds were obtained with Custom Soundâ EP 5.2. Results: Correlations analysis was done between behavioral C levels and eSRT or eCAP separately. For E22, behavioral C level was positively correlated with eSRT (r=.772; p= .009; p < .01) and eCAP (r=0.812; p=.004;
