Electric and Autonomous Vehicle: from Sound Quality to Innovative Sound Design
Résumé
This study follows long-term lines of research and realizations accomplished within the frame of electric vehicle sound design. It currently deals with the most up-to-date issue addressing the near future mobility: Autonomous Drive (AD). It has been implemented in a 2-year collaboration with a french car manufacturer that deployed a high-tech demo-car where the sonic dimension was explored in a spatial and a multisensory approach. Specific hardware devices (multi-channel diffusion system) and software protocols (spatialization and vehicle data transmission) made possible the study and realization of numerous and accurate internal/external warning sounds and auditory Human-Machine Interfaces. The autonomous driving condition was especially considered as it corresponds to an unprecedented user experience in terms of human-centered process, where sounds could play a crucial role for informing and, if necessary, reassuring the driver and passengers. This paper presents a thorough analysis of the project: initial requirements and data, multidisciplinary framework, technical details, sound concepts and realization. It also opens onto reflexive and prospective considerations about the global notion of sound quality that especially look at possible forms of low-intrusiveness in sound design, and their related properties.
