The method involves presenting blind signals i.e. dummy presentations, before and/or between test signals. The blind signals are not provided for loudness-based binaural adjustment of an amplification of left and right hearing aids at a preset level and a preset frequency. The blind and test signals are produced in the hearing aids using a noise generator. The level and frequency are adjusted depending on an accident. The amplification is changed from a distance of evaluation of a hearing aid user to a target category.
