Study summary

The purpose of this study is to assess the effectiveness and optimization of various FDA approved products.

Read the detailed description

This study uses a prospective within-subjects repeated-measures design in which each subject serves as her/his own control. The purpose of this study is to assess the effectiveness and optimization of various FDA approved hardware, signal preprocessing and processing software, fitting characteristics, and service delivery methods, such as remote support and/or tele-audiology on an expanded subject demographic. The insights gained from this study will be used to optimize listening configuration recommendations, refine audiological practice, and inform future innovations.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Ability to provide /Assent
  • Adults (age +18 years) and children (8-17 years) can be enrolled in this study

    • If child is aged 8-17 years, an assent will be completed, and the subject must be accompanied by a parent or legal guardian for all study activities
  • Have the functional capability to operate the controls for the device and to comply with all directions during the study as determined by the investigator conducting the consent/baseline visit
  • English language proficiency as determined by the investigator

Exclusion criteria

Exclusion Criteria:

  • Have any significant medical condition that, in the opinion of any of the investigators, is likely to interfere with study procedures or likely to confound evaluation of study endpoints
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Speech performance in noise

    The primary efficacy endpoint is recorded AzBio sentences presented from a single loud speaker at 60 dBA. The recognition scores using the pinna-located microphone in quiet and noise captured at initial visit will be compared to the AzBio sentence recognition scores using the pinna-simulated microphone. Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome.

    Time frame: 1 day

Secondary outcomes

  1. Localization performance

    A secondary efficacy endpoint is a front/back localization task where filtered pink noise is presented at 60dBA from one of six speakers in a 360 degree array. Scores are generated in percent correct; the scores obtained from the pinna-located microphone will be compared to the localization scores using the pinna-simulated microphone.

    Time frame: 1 day

  2. Analysis of usability and preference questionnaire

    Subject responses captured on a usability and preference questionnaire at the initial visit will be compared to responses on the questionnaire administered after each two-week chronic use interval. Questions will inquire about subject's ability and experience hearing and listening in different situations and wearing configuration preferences. The questions are rated on a 5-point Likert scale with varying strength, such as "It was easy to verify proper microphone function" with answers ranging from strongly disagree to strongly agree.

    Time frame: 8 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2023 (actual). Primary completion is estimated for Apr 2028, 60 months after the start.

Of 125 industry-sponsored interventional studies with no phase under Hearing Loss, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 15. This study's planned 60 months is above that.

Counting every sponsor, half of 321 studies reached it within 19 months; a quarter within 5 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 13, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
