A study testing Phonak, Device A and Device B in people with Hearing Loss, run by Sonova AG at 1 site in United States.
Trial summary
This study will compare far-field speech understanding in noise using a hearing aid alone, with using a hearing aid plus a Roger remote microphone. It will also compare the HA+Roger mic to two other manufacturers' hearing aids plus remote mic systems in the same condition. Read more about this study

About this study
This study will compare far-field speech understanding in noise using a hearing aid alone, with using a hearing aid plus a Roger remote microphone. It will also compare the HA+Roger mic to two other manufacturers' hearing aids plus remote mic systems in the same condition.
Read the detailed description
This study will recruit 15-20 hearing impaired experienced hearing aid adult users. Participants will be fit with three sets of hearing aids (Phonak devices, plus two competitor devices) and the associated remote microphone from each manufacturer. Speech perception will be measured using the validated AZ Bio test, and will be given in both the hearing aid alone condition, as well as the hearing aid plus remote microphone condition. The participant will be seated in the center of a room approximately 7m by 5.25m with a loudspeaker approximately 3 m away, at 0 degree azimuth. Four loudspeakers will also be placed in the corners of the room. For the quiet condition, target speech will be presented from the loudspeaker in front of the participant, for the noise condition speech will be presented from the front with speech babble presented from each of the corner loudspeakers. The speech understanding score in both quiet and in noise will be measured for hearing aids alone, and hearing aids plus the appropriate compatible remote microphone.

What is being measured
The primary outcome is the main question the study is designed to answer.
AZ Bio Sentence Test
Validated test of speech intelligibility in which participants repeat as many words as they can from a presented list of 20 sentences. Words correct are calculated as a percent correct from the total number of words presented. Higher percentages mean better speech intelligibility.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will compare far-field speech understanding in noise using a hearing aid alone, with using a hearing aid plus a Roger remote microphone. It will also compare the HA+Roger mic to two other manufacturers' hearing aids plus remote mic systems in the same condition.
Detailed description
This study will recruit 15-20 hearing impaired experienced hearing aid adult users. Participants will be fit with three sets of hearing aids (Phonak devices, plus two competitor devices) and the associated remote microphone from each manufacturer. Speech perception will be measured using the validated AZ Bio test, and will be given in both the hearing aid alone condition, as well as the hearing aid plus remote microphone condition. The participant will be seated in the center of a room approximately 7m by 5.25m with a loudspeaker approximately 3 m away, at 0 degree azimuth. Four loudspeakers will also be placed in the corners of the room.

The record says: finished, as of the sponsor's last update on 29 May 2026. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
AZ Bio Sentence Test (time frame: Visit 2, Day 2 of study). 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 29 May 2026.
