Zero-Emission Vehicles Sonification Strategy Based on Shepard-Risset Glissando

In this paper, we present a sonification strategy developed for electric vehicles aiming to synthetize new engine sound enhance the driver’s dynamic perception of vehicle. We chose mimic internal combustion (ICE) noise by informing driver through pitch variations. However, ICE variations are correlated engine’s rotations per minute (RPM) and its dynamics is covered within limited vehicle speed range. order provide with extended throughout full range, based our on Shepard-Risset glissando. Such illusory infinite ascending/descending sounds enable represent accelerations significant an unlimited range speeds. way, it possible conserve metaphor unheard gearshifts. tested in perceptual test driving simulator showed that mapping acoustical feedback affects drivers’ dynamics.
