Study Summary
This trial is testing a new way to fit hearing aids that doesn't require the person to come into the clinic, which would be more convenient for patients.
Who is the study for?
This trial is for Veterans aged 18-85 with sensorineural hearing loss, who can understand English and have at least a moderate ability to recognize words in quiet. They should be experienced users of VA-issued hearing aids seeking replacements of the same style and make, without significant ear pathology or recent changes in their hearing level.Check my eligibility
What is being tested?
The study tests if a new fitting approach using a coupler (a device that simulates the ear) for replacement hearing aids is effective. This could allow Veterans to receive their aids by mail without attending an appointment. Different styles of behind-the-ear (BTE) and in-the-ear (ITE) devices are being compared.See study design
What are the potential side effects?
Since this trial involves non-invasive procedures related to fitting hearing aids, there are no direct side effects like those seen with medications. However, participants may experience discomfort or dissatisfaction with the fit or performance of the replacement hearing aids.

Experimental Treatment
Active Control
Group I: Study 3 (experimental open-fit)Experimental Treatment1 Intervention
Experienced hearing aid user receiving replacement receiver in the canal (RIC) or receiver in the aid (RITA) hearing aids with OPEN coupling that are fitted and verified in a test box coupler, then mailed to the patient for a 4-week field trial.
Group II: Study 3 (experimental closed-fit)Experimental Treatment1 Intervention
Experienced hearing aid user receiving replacement receiver in the canal (RIC) or receiver in the aid (RITA) hearing aids with CLOSED coupling that are fitted and verified in a test box coupler, then mailed to the patient for a 4-week field trial.
Group III: Study 1 (In-the-Ear) GroupExperimental Treatment1 Intervention
Experienced users of in-the-ear (ITE) hearing aids will receive replacement ITE hearing aids that are fitted and verified in a test box coupler, then mailed to the patient for a 4-week field trial.
Group IV: Study 1 (Behind-the-Ear) GroupExperimental Treatment1 Intervention
Experienced users of behind-the-ear (BTE) hearing aids will receive replacement BTE hearing aids that are fitted and verified in a test box coupler, then mailed to the patient for a 4-week field trial.
Group V: Study 2 (Open-Fit corrections)Active Control1 Intervention
Participants with hearing loss will be fitted monaurally with 12 stock non-custom, receiver in the canal (RIC) or receiver in the aid (RITA) hearing aids using the standard in-situ approach and test box measures will be made of each fitting to develop correction factors for these styles.
Group VI: Study 3 (open-fit comparison)Active Control1 Intervention
This group will serve as the active comparator group for experienced hearing aid user receiving replacement receiver in the canal (RIC) or receiver in the aid (RITA) hearing aids with OPEN coupling using the standard of care approach, then undergoing a 4-week field trial.
Group VII: Study 3 (closed-fit comparison)Active Control1 Intervention
This group will serve as the active comparator group for experienced hearing aid user receiving replacement receiver in the canal (RIC) or receiver in the aid (RITA) hearing aids with CLOSED coupling using the standard of care approach, then undergoing a 4-week field trial.

Eligibility Criteria:
This trial includes the following eligibility criteria:- You have a problem with your outer or middle ear that can be found during ear exams or hearing tests.Your hearing has significantly worsened, as shown by a hearing test, while using your current hearing aids.Your hearing is about the same in both ears, with no big differences in how well you can hear different pitches.You do not have a phone or do not use a phone.People who already use hearing aids and are getting new ones from the VA that are the same style and brand as their current ones.You have a high score on a test that measures memory and thinking skills.Your hearing loss is not too severe (defined as less than 60 decibels at certain frequencies).Veterans between 18 and 85 years old with hearing loss caused by issues in the inner ear.You have a hearing loss that is not too severe (less than 60 decibels) at certain frequencies.You can understand at least half of the words spoken to you in a quiet environment during a hearing test.People who already wear hearing aids and need to get new ones of the same type and brand from the VA.Your hearing in both ears is similar, with no more than a 20 decibel difference in hearing ability at two different frequencies.We are looking for Veterans between 18 and 85 years old who have hearing loss caused by damage to the inner ear or nerve pathways.Participants in Study 1 and 3 who use hearing aids can only get new hearing aids if they are the same type and brand as their current ones provided by the VA.I'm sorry, but without the specific details of Study 1 and Study 3, I am unable to provide a simplified summary of their screening criteria. Could you please provide more information about these studies?
