Abstract Objective: This study investigates the effect of spectral loudness summation (SLS) in the electrical domain as perceived by cochlear implant (CI) users. Analogous to SLS in the acoustical domain, SLS was defined as the effect of electrode separation at a fixed overall stimulation rate. Design: Categorical loudness scaling (CLS) was conducted at three overall stimulation rates using single-electrode stimuli and multi-electrode stimuli presented interleaved on two or four electrodes.

The results showed that categorical loudness scaling for electric stimulation was similar to that for acoustic stimulation in normal hearing subjects, and could be used as a guide for aligning electric and acoustic loudness in CI recipients with contralateral hearing. Expand
Output compression in cochlear implants: The added value of subject-specific parameter optimization
A cochlear implant (CI) is an electronic device that can provide a sense of hearing to deaf or profoundly hearing impaired listeners by directly activating auditory nerve fibers. Optimal auditoryExpand

Loudness summation for pulsatile electrical stimulation of the cochlea: effects of rate, electrode separation, level, and mode of stimulation.
The aim of these two experiments was to gain systematic data on the amount of loudness summation measured for dual-electrode stimuli with varying temporal and spatial separation of current pulses, consistent with a loudness model in which the neural excitation density is first obtained by temporal integration of excitation at each cochlear place, then converted to specific loudness via a nonlinear relationship, and finally integrated over coChlear place to obtain the loudness.

The relationship between loudness and ECAP growth functions, the curvature versus MCL function and the loudness associated with threshold are relevant to the development of a mathematical model of electrically evoked auditory nerve excitation. Expand
Speech Perception as a Function of Electrical Stimulation Rate: Using the Nucleus 24 Cochlear Implant System
Results from one subject, together with tinnitus problems arising from high-rate stimulation for another subject, indicated that high rates of stimulation may in fact be undesirable for some subjects, and individual results indicated that perceptual benefits could be obtained by adjusting rate of stimulation optimally to suit each subject.

Cochlear-implant spatial selectivity with monopolar, bipolar and tripolar stimulation
The present model is of high clinical significance in terms of predicting and improving cochlear-implant performance and significant correlation was found between the individual physiological and psychophysical tuning widths, and the correlation was improved by log-linearly transforming the physiological data to predict the psychophysical data.

A practical method of predicting the loudness of complex electrical stimuli.
A practical method of calculating loudness estimates for multiple-electrode cochlear implants using the simplifying approximation that current pulses falling within a temporal integration window of several milliseconds' duration contribute independently to the overall loudness of the stimulus.

Effects of pulse rate and electrode array design on intensity discrimination in cochlear implant users.
The observed effects of pulse rate and electrode array design may stem primarily from an inverse relationship between absolute current amplitude and the size of intensity DLs, which could be the result of increased variability of neural outputs in these subjects. Expand
