Study Summary
Hearing loss is among the top service-connected disabilities in Veterans. Hearing aids are the primary intervention for hearing loss. Half of the hearing aids dispensed in the VA are to Veterans who are receiving replacement amplification. Many Veterans would like their replacement hearing aids mailed to them, but they are required to travel to the clinic so that the fit of the hearing aid can be verified. There are standard fitting procedures, such as those used in infants and children, that use a coupler to simulate the patient's real ear to verify the hearing aid fitting. The results of this study should determine the efficacy of a coupler-based hearing-aid fitting protocol that would not require the Veteran to attend the fitting appointment, thereby contributing to improved Veteran-Centric care.
Primary Outcome
The primary outcome of interest is based on fitting accuracy across ears (i.e., the averaged absolute deviation from target of the average of 500, 1000, 2000, and 4000 Hz across both ears measured in decibels (dB)).
Interventions
- DEVICE Study 1 - ITE hearing aids
- DEVICE Study 1 - BTE hearing aids
- DEVICE Study 3 (open-fit comparison)
- DEVICE Study 3 (closed-fit comparison)
- DEVICE Study 3 (experimental open-fit)
