\nsignal processing became available in hearing aids. However, many users still experience
\ndifficulties in noisy environments and in complex listening scenarios. Although numerous
\nparameters can be adjusted to provide an individualized hearing solution, hearing-aid fitting
\ncurrently consists of: 1) the gain prescription and adjustment based on the pure-tone audiogram, 2)\u00a0the activation of advanced features on-demand, such as beamforming and noise reduction. In a\u00a0previous study [1], a novel approach for auditory profiling was suggested, where the hearing deficits\u00a0were characterized according to two types of distortion. This allowed the classification of listeners\u00a0into four auditory profiles according to a high\/low degree of hearing distortions along the two\u00a0dimensions. The aim of the present study was to evaluate different hearing-aid compensation\u00a0strategies that may fit the needs of different auditory profiles via technical measures. A hearing-aid\u00a0simulator, consisting of beamforming, noise reduction, and dynamic range compression, was used\u00a0to test which parameter spaces and outcome measures may be of interest for a \u201cprofile-based\u00a0hearing-aid fitting\u201d. The simulator consists of two dummy behind-the-ear hearing aids and off-line\u00a0sound processing performed on a personal computer. Technical measures, such as signal-to-noise\u00a0ratio (SNR) improvement, envelope degradation, and a metric of spectral distortions, were used to\u00a0evaluate the effects of different signal processing strategies on the signal at the output of the\u00a0simulator. Several parameter settings were evaluated using speech in the presence of various\u00a0interferers at different SNRs. Here, the results of this technical evaluation are presented and\u00a0discussed, with a view towards identifying the effective compensation strategies for different\u00a0auditory profiles.<\/p>\n
