: Modern digital hearing aids provide unprecedented means of compensating for hearing impairments. However, this comes at the price of adjusting complex processing parameters. To achieve an individual optimum, all processing parameters have to be carefully pre- and re-adjusted. The required time and effort can often not be made available. To provide an independent means of optimizing speech intelligibility, we developed a dedicated solution using mostly off-the-shelf hardware and a dedicated software. With this, a pc-literate hearing impaired person can independently check his aided speech reception. The result can be a valid basis for improvement of the hearing instrument parameter adjustment.
