Mainz – November 03, 2026 -- Hearing aids that go silent, fade, whistle or slip out of the ear often have simple causes, and some can be fixed at home, according to Eberhard Schmidt, president of the Bundesinnung der Hörakustiker (biha). Poor fit and disruptive noises are common reasons people stop wearing their devices, even though individually fitted systems enable social participation for people with hearing loss.
