With the introduction of UN Regulation No. 138, the audible detectability of electric vehicles became a mandatory component of vehicle design. The version currently under revision, 138.02, reveals that the discussion regarding the future direction of noise emissions is a contentious one—ranging from reducing to increasing noise emissions, as well as expanding the relevant speed ranges. The presentation highlights that sound design for electric vehicles is not only a legal requirement for pedestrian safety but also makes significant contributions to driving safety and the user experience. With the elimination of traditional acoustic feedback from the electric powertrain, the driver loses an important sensory link to the vehicle’s operating state. Strategies and algorithmic approaches for designing synthetic driving sounds can address this issue by supporting both emotional engagement and the intuitive perception of the vehicle’s operating state. This paper discusses methodological approaches to sound design that balance safety, acceptance, and brand identity, and demonstrates how targeted acoustic design forms the interface between technical necessity, user experience, and regulation.
