[Factorial structure of discriminating speech perception in binaural electro-acoustic correction in patients with imparied hearing of various etiology].

These authors examined 260 patients with hypoacusis of various etiology who needed hearing aids. When measuring their hearing, the authors identified the basic factors that may influence speech intelligibility in the case of binaural correction and optimal type of hearing aids. For every group of patients with hypoacusis of various etiology regression curves of integrated parameters were plotted which helped predict the effectiveness of hearing aids on an individual basis.
