The project drivEkustik was funded from 2012 to 2013 by the Austrian Ministry for Transport, Innovation and Technology (BMVIT) in order to analyse the driving behaviour and the acoustic perception of electric vehicles (EV) in relation to vehicles with an internal combustion engine (ICE) with special focus on visual impaired people (VIP). In the frame of work package 1, pass-by measurements based on the standard ISO 362 have been carried out to compare the sound emission and the acoustic detectability of di erent cars. The measurements were performed using four di erent vehicles, while the investigated speed range was between 10 and 50 km/h. All measurements were carried out with conventional microphones and a binaural head. The binaural recordings were supplemented with recordings of di erent environments (rural back-road, suburban back-road, urban back-road, urban trough-road and parking situation), in order to perform a laboratory listening test to determine the detectability of the vehicles. The measurement results were analysed and compared with the outcomes of the listening test. A statistical analysis of the listening test with focus on the di erence between the detection times was also carried out. An additional comparison between VIP and sighted people was performed for the investigated situations. In the present paper the main results of this work are presented.
