Efficacy of a Coupler-Based Hearing-Aid Fitting Approach for Experienced Users
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.
outcomes between the traditional, fitting approach where the patient is present during the

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.
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.

Inclusion Criteria:
- no more than a moderate sensorineural hearing loss (defined as < 60 dB HL pure-tone
average at 500, 1000, and 2000 Hz AU)
- experienced BTE hearing-aid users who are obtaining replacement VA-issued BTE hearing
aids coupled to a custom earmold that is simply an upgrade in model with the same
style earmold
- ability to read and write in English as determined by reading a few sentences from
the consent document aloud so that self-report measures can be completed
Exclusion Criteria:
- outer or middle ear pathology as determined by otoscopy, immittance, and/or
audiometric testing (e.g., conductive or mixed losses)
- lack of phone or non-use of the phone as the participants will be required to conduct
a telephone interview after they obtain their replacement hearing aids
- unwilling or unable to be mailed hearing aids
- co-morbid condition that would preclude their participation as determined by a chart
