An elevator arrangement has a car displaceable within an elevator shaft between building floors, an elevator control and a fixture located at each floors and connected to the elevator control for an exchange of information. Each fixture includes a sound detector detecting sound propagating within the shaft. The arrangement performs a fixture position learning procedure by determining position information for each fixture based on sound characteristics detected by the sound detector and storing the determined position information for subsequent identification of each of the fixtures. Changes in sound characteristics are detected while the car is displaced through the shaft. Time-dependent occurrences of sound pressure peaks or frequency shifts due to Doppler effects are measured at the fixtures and fixture position information is derived from a sequence order of such occurrences or, alternatively, by correlating the occurrence of sound characteristic changes with current car position information provided by the elevator control.
