[SISI-Test and functional hearing loss (author's transl)]

The original SISI test (Jerger, Shedd and Harford) is described in German language. Modifications of various authors are cited. The results of SISI test with 16 persons demanding monetary compensation for hearing loss are tabulated. 18 ears seemed free from non-organic overlay. 12 of those ears gave SISI scores more than 70%. Functional discrepancies wer observed in 13 ears. Only in one of them a maximum SISI score of 25% was presented. All other non-organic ears gave lower ratings, 0% in most cases. Increments of 5 dB were not responded with 5 ears. In one case of unilateral non-organic loss SISI scores were high in the normal and low in the aggravating ear. It is suggested therefore, that low SISI ratings should arise suspicion of non-organic problems, besides of retrocochlear site.
