Cochlear Implant Users
Conditions
Brief summary
This observational study will examine newly activated cochlear implant users and determine whether their abilities to discern simple sounds change and relate to improved speech perception. Take-home computers and test-equipment will be sent home, and subjects will complete approximately 25 test sessions over the first 3 months of cochlea implant use. Then, subjects will be tested 3 more times in the laboratory until 1 year-post activation. The primary objective is to determine and quantify how sounds change and speech perception improves over the course of early cochlear implant use.
Interventions
OTHERTake home tests
These tests will test the discriminability of sounds that vary systematically along the frequency and temporal dimensions of sound. Over the course of the 3 months post-activation, subjects will self-complete "take-home" tests at location of their choosing. Each test session will include the entire test-battery will be repeated frequency as often as every day and then reducing frequency of testing corresponding to the rate of speech perception improvement.

Inclusion criteria
1. Postlingually deaf cochlear implant users 2. severe or profound hearing loss 3. who do not have other diagnoses communicative or cognitive disorders. 4. Test population: no prior experience with cochlear implants (recruitment happens prior to cochlear implantation). 5. Control population: subjects who have used the same stimulation strategy since initial stimulation, who note no continuing improvements or changes with their devices with respect to speech comprehension.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in percentage of correct responses during speech perception tests | Baseline, 1 year | Speech perception tests involves presentation of a speech stimulus (may be a word, sentence, nonsense words, or other speech sounds) and subjects will have to indicate what they heard. The total score is the percentage of speech stimulus correctly understood, ranging from 0-100%. |
