Nowadays, there has been a growing interest in virtual reality (VR) technology in the automotive industry, for the virtualization of new vehicle development. This solution allows us to reduce the number of prototypes to be built, increasing the tested cases and at the same time significantly reducing costs and time. In this paper, a methodology is presented to achieve a complete VR auralization of an Active Vehicle Alert System (AVAS) installed on an electric vehicle. A passing maneuver at different speeds was recorded using a duallens camera and a spherical microphone array (SMA), while a smartphone inside the car also recorded the position with a specifically developed application. A virtual test environment was developed to auralize the car maneuver in real-time, also considering the directivity and frequency response of the AVAS speaker, the Doppler effect and the reflection on the road. In this way it is possible to immediately replace the type of transducer and sound to be reproduced, allowing the result to be evaluated with immersive tests having a high degree of realism. The future outcome of the research presented will consist of jury tests to objectify the choice of AVAS sounds, based on the different perception of appreciation of people in various countries of the world, also in relation to the type of vehicle. In addition, it will be possible to identify the most perceptible sounds, thus increasing the safety and effectiveness of AVAS itself.
