title: [SISI or differential limen test - tests for recruitment (author's transl)].
abstract: The detection of recruitment is based on investigating change of loudness with change of intensity. The evaluation and further differential diagnosis of inner ear damage is, for instance, a necessity in an expert opinion of an ENT specialist. Which of the numerous methods of detecting recruitment can be recommended for the specialists practice. Over 215 patients with inner ear damage were tested for recruitment with different test methods. Results showed that SISI tests were performed with more accuracy than differential limen tests. Differences of various recruitment methods of our collective are investigated and advantages and disadvantages discussed. The recommendation for the specialists practice would be to perform 1. the "limits of intensity" (threshold of hearing and loudness discomfort), 2. the supraliminal noise-audiometry Langenbeck and 3. the SISI test. They seem to be most effectful, exact, reproducible and easy to perform test-methods for detecting recruitment.
