Summary 120 caloric vestibular tests (50 ml water of 30° resp. 44° in 30 s) were carried out on 30 normal persons 20—30 years of age. The responses were analyzed as to the reliability of evaluation using Frenzel's glasses, in case of a limited evaluation to a defined observation period. This observation period was located at different time-intervals after stimulation and compared to the maximal phase of reaction registered by ENG simultaneously. The difference between the number of beats within the fixed observation period and the number of beats within the maximal phase of reaction was defined as the rate of error. The interval (20, 50) s after the end of stimulation was highly qualified to present the intensity of the vestibular response. As some reactions are very slow and finished before the 20th s the interval (10, 70) s was suggested, too. The intervals (20,50) — and (10,70) s showed low rates of error and high correlation to the maximal reaction. This method can be used for clinical routine. Difficult problems can only be answered by more elaborate proceedings.
