An interventional study of Mobile Research App (MRA) and SOC/validated delivery of the speech perception test material in Hearing Loss, sponsored by Cochlear. Recruiting at 4 sites in 3 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-30.
Sponsored by Cochlear · Not applicable, Interventional, and Basic science
The study is a feasibility, prospective, repeated-measures, multi-country, multi-centre, study of the Mobile Research App to measure and validate speech perception endpoints in adult cochlear implant recipients.
1,092 studies on the registry are indexed under Hearing Loss; 235 are open to participants now.
This study's planned enrollment of 46 is above the median of 40 across 764 interventional studies indexed under Hearing Loss.

Exclusion Criteria:
Cochlear implant recipients will participate in this arm (sub-investigation AI5841A).
Device: Mobile Research App (MRA) · Other: SOC/validated delivery of the speech perception test material
Cochlear implant and hearing aid recipients will participate in this arm (sub-investigation AI5841B).
Device: Mobile Research App (MRA) · Other: SOC/validated delivery of the speech perception test material
The MRA (research tool) is a platform used for the delivery of speech perception material in-clinic outside the sound booth or in the home of the hearing-impaired recipients. The MRA speech testing module delivers speech material via streaming to the single implanted ears of cochlear implant recipients. The recipient listens to the speech material and responds with what was heard via the app. Speech is streamed via Bluetooth from the iOS device to the sound processor of the CI-recipient.
This involves the delivery of speech perception test material in the sound booth in a clinic.
Percent correct performance for the test and retest runs of speech perception ability
To determine if test-retest reliability with a correlation greater than or equal to 0.8 can be achieved for speech perception ability measured on the MRA outside the sound booth, percent correct performance for the test and retest runs of the speech perception ability will be compared. Scoring: Percentage correct Range: 0-100%, higher scores equal better performance
Time frame: 1 day - immediately post screening.
