[The "negative" SISI-test (author's transl)].

The SISI-test has gained increased recognition during the past few years and can now be considered as the most important recruitment hearing test. In addition to the positive, negative and not determinable result there are frequent cases of incorrect negative interpretation. A "negative" SISI-test can be the result of insufficient or excessive hearing loss, missing adaptation, pathological threshold shift, aggravation, psychogenic deafness, cerebral sclerosis, imbecility etc. A negative result always requires additional audiometric differential-diagnosis.
