Summary
The efficiency of SISI test for audiological evaluation of hearing impairment is investigated by a retrospective study of 604 subjects. In addition to the dependence of SISI scores on the age of the subjects the influence of sound pressure level and frequency is discussed. Comparing SISI results with those of other special tests (Fowler, Langenbeck) we find that SISI test tends to indicate haircell lesions even though other tests exhibit a different site of the lesion. Particularly in cases of complex hearing impairments (noise plus other causes) SISI test frequently shows false-positive results. Therefore SISI scores should be interpreted carefully, especially with regard to legal examination of noise induced hearing loss.
