About this study

Official title: Web App Fitting Strategy Validation NSR Device Study

To be conducted with adult participants with mild-to-moderate hearing loss to validate the effectiveness of the Web App fitting strategy. Validation measures participant's perceived hearing aid benefit when using the Web App fitted hearing aids and when using standard-of-care fitted hearing aids.

Read the detailed description

A prospective, randomized controlled, adaptive design, non-inferiority, pre-market and NSR device study. Completed in 26 adult subjects with mild-to-moderate hearing loss to validate the effectiveness of a Web App fitting strategy. Validation measured subject´s perceived hearing aid benefit when using the Web App fitted hearing aids and when using standard-of-care fitted hearing aids.

The adaptive study design began with a cross-over design of the first 12 subjects. At the interim analysis, the possibility of an interaction effect was evaluated as a nuisance parameter. In the absence of an interaction effect, the study was completed in cross-over design.

The standard-of-care fitted hearing aids were fitted to National Acoustic Laboratories Nonlinear Version 2 (NAL-NL2) prescriptive targets, verified by probe-mic real-ear measures (REM). The null hypothesis (H0) was that subject´s perceived hearing aids benefit using Web App fitted hearing aids is inferior to perceived benefit using standard-of-care fitted hearing aids, and the alternative hypothesis (Ha) was that subject´s perceived hearing aids benefit using Web App fitted hearing aids is non-inferior to that using standard-of-care fitted hearing aids.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Abbreviated Profile of Hearing Aid Benefit (APHAB)

    The APHAB consists of 24 questions across 4 subscales: Ease of Communication (EC), Background Noise (BN), Reverberation (RV), and Aversiveness (AV), assessing hearing difficulties in daily situations reported as percentage of problems (0-100%, 100% = highest number of problems). It evaluates hearing aid (HA) benefit by subtracting the reported % of problems with HA from without HA, yielding scores from 0 (no benefit) to 100 (maximum benefit) in each subscale. The study focuses on the communication subscales (EC, BN, RV) and calculates benefit score differences for each subscale after using A) Web-App-fitted and B) standard-of-care-fitted HAs. The difference-of-benefit scores are compared to non-inferiority margins from Cox\&Alexander (Ear\&Hearing 1995). Differences-in-benefit scores range from -100 to 100, with negative scores indicating greater benefit with Web-App-fitted HAs, 0 indicating identical benefit and higher scores indicating greater benefit with standard-of-care fitting.

    Measured: 14-17 Days hearing aid wearing time per fitting type

Questions about this trial

What is this clinical trial studying?

A study testing Web App Strategy Fitting and Standard-of-care Fitting in people with Hearing Loss, Sensorineural, run by WSAUD A/S at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Abbreviated Profile of Hearing Aid Benefit (APHAB) (time frame: 14-17 Days hearing aid wearing time per fitting type). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025; AzTrials last refreshed its copy on 30 Oct 2026.
