NCT07114744

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.

Outcome Measures

Primary Outcomes (1)

  • Change in percentage of correct responses during speech perception tests

    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%.

    Baseline, 1 year

Study Arms (2)

Newly Implanted Users

Participants have no prior experience with cochlear implants (recruitment happens prior to cochlear implantation) will complete at home testing (\~25 sessions) over \~3 months of implant use.

Other: Take home tests

Experienced Cochlear Implant Users

Participants who have used the same stimulation strategy since initial stimulation will complete at home testing (\~25 sessions) over \~3 months of implant use.

Other: Take home tests

Interventions

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.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The population includes hearing impaired adults. Both genders will be recruited. All subjects will be recruited from the NYU Cochlear Implant Clinic.

You may qualify if:

  • Postlingually deaf cochlear implant users
  • severe or profound hearing loss
  • who do not have other diagnoses communicative or cognitive disorders.
  • Test population: no prior experience with cochlear implants (recruitment happens prior to cochlear implantation).
  • 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.

You may not qualify if:

  • Diagnosed cognitive or communicative disorders (other than deafness)
  • Below 18 years of age
  • Above the age of 85 years old.
