[Results of the SISI test and Békésy audiometry in pseudohypacusis (author's transl)].

The terminology of pseudohypacusis is used for the syndrome of gaps between possible audiometric response and performance in testing. No etiology in psychological terms is defined for pseudohypacusis, although monetary compensation has been considered as a possible factor. SISI ratings of 0% in most instances (ranging to a maximum of 25%) have been observed. Békésy-audiometry produced Types I, II, IV and V tracings as well as unclassified curves, although the type V tracing is most commonly found. Results of fixed frequency Békésy-audiometry have also shown a shift of curves for continuous and interrupted tones (called "Type VI"). In some cases Type V and Type VI tracings were found in the same ears. The causes and psychoacoustic phenomenon involved remain unexplained.
