Can a smartphone app replace the clinic for hearing aid tuning?
NCT ID NCT06992778
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers in Denmark are testing whether people with hearing aids can fine-tune them remotely using a smartphone app instead of visiting a clinic. The trial enrolls 120 adults with hearing loss who are comfortable using smartphones. Participants are randomly assigned to either remote fine-tuning from home or standard face-to-face adjustments, with five visits over three months. The study measures self-reported hearing, satisfaction, and speech understanding to see if remote care works as well as in-person care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Remote fine-tuning of hearing aids through a smartphone app
- What this could lead to
- If remote fine-tuning works as well as clinic visits, people with hearing aids could adjust them from home, saving trips and fitting care into daily life.
- What could go wrong
- This is a small, non-blinded study in Danish adults who are comfortable with smartphones, so results may not apply to everyone. Remote adjustments might not match in-person care for all users or hearing aid models.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patients with hearing loss who desire HA treatment (+18 of age). * Danish language skills both written and oral. * Acquisition of digital proficiency in terms of being familiar with operating a smartphone, including navigating menus, opening and closing apps, and interacting with the touchscreen with capabilities for audio and video calls. * Access to a smartphone that are compatible with manufacturers' system requirements. * Access to a stable network connection on the mobile device, with either Wi-Fi or mobile data. Exclusion Criteria: * Patients with tinnitus requiring treatment or scoring more than 58 in the 'Tinnitus Handicap Inventory' (THI) grading system. * Patients with Ménière disease, due to its complications and symptoms as dizziness, balance problems and fluctuating hearing loss, that can affect the HA treatment. * Patients who will receive in-the-ear (ITE) hearing aids, due to potential limitations in connectivity for remote fine-tuning. * Patients which are recommended/offered unilateral HA treatment.
