Clinical Trial Summary

This clinical investigation is designed to compare audiological performance (i.e., measurements of sound quality and speech understanding) between Starkey's new receiver-in-canal device and a commercially available legacy receiver-in-canal device.

Description:

Starkey is investigating a new hearing aid with several new audiological features. These features have been assessed for benefit, individually, but this clinical investigation will serve as a test for safety and efficacy with all hearing aid features, together. The design of this study is a single-blinded, crossover design and will be conducted at Starkey's headquarters in Eden Prairie, MN.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Speech intelligibility (% words repeated back correctly) in quiet and noise for new vs. legacy hearing aids	IEEE sentences will be presented to the research participants in quiet and in background noise. The percent words repeated back correctly will be scored and serve as the reported result of this outcome measure.	Four weeks
Secondary	First fit ratings of sound quality on subjective questionnaires for the new vs. legacy hearing aids	This data will be collected through lab testing following the first fit of the hearing aids. Participants will answer questionnaire items related to their impressions of sound quality. Results will be collected using a 7-point Likert scale, and ratings (1-7) will be analyzed using descriptive statistics. Statistical measures for repeated measurements will be used to understand any differences between hearing aid conditions.	Four weeks
Secondary	Safety of the new, receiver-in-canal devices through tracking of adverse events	This data will be collected through the tracking of adverse events.	Four weeks
