Perceptual Consequences of Cochlear Implant Electrode-neuron Interfaces
March 12, 2024 updated by: Julie G. Arenberg, CCC-A, Massachusetts Eye and Ear Infirmary
Development and Assessment of Listener-tailored Programming for Cochlear Implant Listeners
Despite the success of cochlear implants, devices surgically placed in the inner ears of patients with severe hearing loss, there remains substantial variability in the overall speech perception outcomes for the children and adults who receive them.
The main goals of this project are: i) to improve our understanding of how cochlear implants affect the developing auditory system, ii) apply that knowledge to test new methods for programming children and adults, and iii) to study how long it takes listeners to adapt to new cochlear implant programs over the short- and long-term.
The results will improve our understanding of how the deafened auditory system develops with cochlear implant stimulation and advance clinical practice to improve hearing outcomes in cochlear implant listeners.

Intervention / Treatment |
---|---|
Experimental: Intervention to assess CI
To develop new programming strategies for individuals that will improve performance for a wider range of cochlear implant people
|
Subjects will be asked to complete this one-page cognitive test assesses short-term memory recall and attention.
This test takes approximately 10 minutes.
Subjects will be asked to listen for the softest sound they can hear ("threshold') with different electrode configurations
Subjects will be asked to determine the difference between different types of sounds, such as those that vary in pitch and/or volume.
Sometimes they will be asked to judge the sound quality of sounds that have very small differences, or make loudness judgments and comparisons.
Subjects will be asked to listen to words and sentences in quiet and/or in the presence of background noise.
For this task they will be asked to repeat the words or sentences following its presentation or use the computer mouse to respond.
Subjects who wear a cochlear implant, for each cochlear implant channel or pair of channels, measurements will be made from other available electrodes in their implant.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Slopes of the spread of excitation of the electrically evoked compound action potential responses
Time Frame: Baseline
|
Responses of the auditory nerve can be measured directly from the cochlear implant using software developed by the implant manufacturer.
By changing the distance between two electrodes, we can quantify the spread of activation in the cochlea.
|
Baseline
|
Slopes of a behavioral measure of spectral resolution called psychophysical tuning curves.
Time Frame: Baseline
|
A behavioral test designed to measure how spectral information is processed in the auditory system.
By changing the relationship between a masker and target signal, we can assess resolution.
|
Baseline
|
Changes in vowel identification scores
Time Frame: Baseline and weekly for 10 weeks after the intervention
|
Medial vowel identification performance in background noise.
Participants will complete age-appropriate testing.
|
Baseline and weekly for 10 weeks after the intervention
|
Changes in sentence recognition scores
Time Frame: Baseline and weekly for 10 weeks after the intervention
|
Speech perception testing includes sentence recognition in noise.
Participants will complete age-appropriate testing.
|
Baseline and weekly for 10 weeks after the intervention
|
Changes in speech-gap detection thresholds
Time Frame: Baseline and weekly for 10 weeks after the intervention

|
Baseline and weekly for 10 weeks after the intervention
|
Changes in time (weeks) with programming strategy
Time Frame: Baseline and weekly for 10 weeks after the intervention

Time Frame: Baseline, and weekly for 10 weeks after the intervention
|
The IT-MAIS is a study-team-guided parental report about how infants and toddlers are responding to sound.

|
