Résumé |
The silence of Quiet Vehicles – especially, Hybrid or Electric Vehicles – is a crucial issue in terms of safety, ergonomics or even ecology which becomes to be largely studied either in a research or development point of view. Most of the works done in that domain are based on experiments which try to measure presence and emergence of such vehicles in real, or simulated, environment and to evaluate their detectabilty, in the same contexts, while being equipped with extra sounds specifically designed for fulfilling basic functional conditions with regards to nearby pedestrians or other road users. In this necessary experimental workflow, we assume that simulation approach – or, more generally, virtual reality – is a potentially powerful and valid paradigm to test the contextual impact of a large number of propositions and to conduct controled laboratory experiments for evaluation. This paper will then present the first step of the development of an audio simulation based on Ambisonics field recordings in various urban locations, multi-channel audio rendering and mock-up of different audio scenarios for insertion of one or multiple QV sound signatures in a given sound scene. Next steps – together with general stakes and perspectives – of this approach will also be presented and discussed. |
