The paper describes first limitations of the clinical hearing aid fitting process. The audiological assessment in this process is based both on classical methods that use as a basis results of the audiometric test and the loudness scaling method. These methods employ artificial test signals. However, the fitting of hearing aids should be also performed on the basis of testing speech understanding in noise, because this is much closer to the real life conditions. A satisfying reliability of these tests may be achieved through the use of modern computer technology with application of a properly calibrated sound system. A new strategy applicable to fitting prostheses was developed. It allows finding automatically characteristics of a hearing aid matching patients needs. The principles of the fitting method, and results of the experiments will be also presented in the paper.
