[Speech intelligibility tests in cochlear implant patients].

The investigation of speech intelligibility under quiet and noisy conditions is essential to evaluate the auditory and verbal rehabilitation of cochlear implant patients. A set of audiological tests is introduced that has been validated and optimized by empirical investigations in adult cochlear implant users. The Kiel logatom test, the Freiburg speech intelligibility test and the adaptive measurement of speech perception threshold in noise with the Oldenburg sentence test are methods suggested for clinical use, which are also applicable for scientific investigations. The test battery provides results that can be interpreted by every professional involved in the rehabilitation process of cochlear implant patients.
