What is being measured
The primary outcome is the main question the study is designed to answer.
Aided Hearing Thresholds for Single Sided Deafness
Aided-hearing thresholds represent the softest sound that the participant can hear inside the audiometric test booth when using a hearing device. Aided hearing thresholds were measured using the participant's own device on their abutment and the Adhear device in the test booth on day 1. Hearing thresholds were measured in hertz.

Higher scores denoted positive responses. The reported values represent an average across the multiple domains of the questionnaire.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
A study testing Adhear Bone Conduction System and Bone anchored hearing aid (BAHA) in people with Hearing Loss, Conductive and Hearing Loss, Unilateral, run by University of Miami 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 10 inclusion and 10 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: stopped early, as of the sponsor's last update on 8 Aug 2023. 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 8 Aug 2023). 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?
Aided Hearing Thresholds for Single Sided Deafness (time frame: Day 1). The study lists 5 primary outcomes in all. 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 8 Aug 2023.
