A small group of cochlear implant users, having normal hearing in the unimplanted ear, compared the pitches of electrical and acoustic stimuli presented to the two ears. Comparisons were between 1031‐pps pulse trains and pure tones or between 12‐ or 25‐pps electric pulse trains and bandpass filtered acoustic pulse trains of the same rate. Three methods (pitch adjustment, constant stimuli, and interleaved adaptive procedures) were used. For all methods, we showed that the results can be strongly influenced by non‐sensory biases arising from the range of acoustic stimuli presented, and proposed a series of checks that should be made to alert the experimenter to those biases. We then showed that the results of comparisons that survived these checks do not deviate consistently from the predictions of a widely used cochlear frequency‐to‐place formula or of a computational cochlear model. In one case, the matches were reliable enough to successfully reveal the movement (slippage) of the electrode array. We also... |
