About
The overall aim of the study is to compare the verification accuracy and hearing-aid outcomes between the traditional, fitting approach where the patient is present during the visit and a coupler-based fitting approach where the patient is not present and mailed their hearing aids. If the coupler-based fitting protocol tested in this study as effective as the traditional fitting protocol, then patients receiving replacement hearing aids may circumvent a face-to-face visit.
Full description
This study will incorporate a verification technique that simulates the patient's actual ear during probe microphone verification measurements, called real-ear to coupler difference (RECD). Because the patient's ear is not used during the RECD measurement, but rather simulated, the patient would not need to be present during the RECD verification. This RECD hearing aid verification can occur in the clinic after which the hearing aids will be mailed to the patient. This study will compare the fitting accuracy and outcomes between the two approaches.
