Objectives: This study measured the impact of auditory spectral resolution on listening effort.
Systematic degradation in spectral resolution was hypothesized to elicit corresponding …

A growing number of laboratories are using research interfaces to conduct experiments with
cochlear-implant (CI) users. Because these interfaces bypass a subject's clinical sound …

The efficacy of cochlear implants is limited by spatial and temporal interactions among
channels. This study explores the spatially restricted tripolar electrode configuration and …

This study examines patterns of auditory cortical activity elicited by single-pulse cochlear
implant stimuli that vary in electrode configuration, cochlear place of stimulation, and …

Background Multichannel cochlear implants give better speech understanding than single-
channel devices. They are intended to make use of the tonotopic organization of the cochlea …

Abstract The House Ear Institute (HEI) had a long and distinguished history of auditory
implant innovation and development. Early clinical innovations include being one of the first …

The partial tripolar electrode configuration is a relatively novel stimulation strategy that can
generate more spatially focused electric fields than the commonly used monopolar …

A model was developed to simulate acoustically the effects of excitation spread in cochlear
implants (CI). Based on neurophysiologic data, the proposed model simulates the electrical …

Psychophysical measurements were performed in three hearing-impaired adult subjects
implanted with a CI22 cochlear prosthesis (Cochlear Ltd.) fitted with a developmental peri …

A potential shortcoming of existing multichannel cochlear implants is electrical-field
summation during simultaneous electrode stimulation. Electrical-field interactions can …
