About this study

Official title: A Study to Compare Patient Perceptions of Two Different Hearing Aid Signal Processing Philosophies

Participants will be fit with each of two hearing instruments in an ABA cross-over design. The study will consist of a total of three approximately 10-day home trials with the devices. Participants will be asked to provide qualitative feedback to investigators regarding the performance of and their preference for each hearing instrument.

Conditions: Hearing Loss, Sensorineural
Being tested: Receiver-in-canal hearing instrument; Manufacturer A, Receiver-in-canal hearing instrument; Manufacturer B
Medical subject headings: Hearing Loss, Sensorineural

What is being measured

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

Standardized Validated Questionnaire Measuring Hearing Aid Sound Quality for First Study Set Worn, i.e. Study Set A for Arm A-B-A and Study Set B for Arm B-A-B
Qualitative feedback questionnaire to gather feedback on particular areas of focus. Subjects will rate hearing performance and sound quality on a Likert scale with lowest number equivalent to worst performance or worst sound quality (1) and higher number equivalent to best performance or best sound quality (10).
Measured: End of home trial 1 (Day 10 of study)
Standardized Validated Questionnaire Measuring Hearing Aid Sound Quality for Second Study Set Worn, i.e. Study Set B for Arm A-B-A and Study Set A for Arm B-A-B
Qualitative feedback questionnaire to gather feedback on particular areas of focus. Subjects will rate hearing performance and sound quality on a Likert scale with lowest number equivalent to worst performance or worst sound quality (1) and higher number equivalent to best performance or best sound quality (10).
Measured: End of home trial 2 (20 days after study start)
Standardized Validated Questionnaire Measuring Hearing Aid Sound Quality for Third Study Set Worn, i.e. Study Set A for Arm A-B-A and Study Set B for Arm B-A-B
Qualitative feedback questionnaire to gather feedback on particular areas of focus. Subjects will rate hearing performance and sound quality on a Likert scale with lowest number equivalent to worst performance or worst sound quality (1) and higher number equivalent to best performance or best sound quality (10).
Measured: End of home trial 3 (30 days after study start)
Standard Validated Questionnaire Measuring Satisfaction of Hearing Aid Performance and Features for First Study Set Worn.
Measures satisfaction on various aspects of hearing aid use on a scale from 1 to 5, with 1 = Very unsatisfied to 5 = Very satisfied, and 3 = Neutral.
.
Measured: End of home trial 1 (Day 10 of study)
Standard Validated Questionnaire Measuring Satisfaction of Hearing Aid Performance and Features for Second Study Set Worn.
Measures satisfaction on various aspects of hearing aid use on a scale from 1 to 5, with 1 = Very unsatisfied to 5 = Very satisfied, and 3 = Neutral.
Measured: End of home trial 2 (Day 20 of study)

Questions about this trial

What is this clinical trial studying?

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 2 inclusion and 2 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 22 Mar 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 22 Mar 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?

Standardized Validated Questionnaire Measuring Hearing Aid Sound Quality for First Study Set Worn, i.e. Study Set A for Arm A-B-A and Study Set B for Arm B-A-B (time frame: End of home trial 1 (Day 10 of study)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04839289.

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 22 Mar 2023; AzTrials last refreshed its copy on 29 Oct 2026.
