EV warning sounds more annoying in groups, new study finds
Multiple EV AVAS sounds increase perceived annoyance compared to single vehicles
Deep Dive
Researchers studied how multiple electric vehicle AVAS sounds affect annoyance perception, shifting from isolated sound design to a scene-based approach. Binaural listening tests used recorded EV pass-by sounds, presenting single and multi-vehicle traffic scenarios, including vehicles approaching from opposite directions. Participants rated perceived annoyance, enabling comparison between isolated and multiple AVAS sound scenarios, investigating how overlapping sounds affect annoyance when multiple EVs pass by.
Key Points
- Binaural listening tests used recorded EV pass-by sounds in single and multi-vehicle traffic scenarios.
- Multiple AVAS sounds from vehicles approaching opposite directions caused higher annoyance than individual sounds.
- Authors call for scene-based AVAS design to replace isolated per-vehicle testing currently mandated by regulations.
Why It Matters
As EV adoption grows, cumulative AVAS noise could worsen urban annoyance; regulations need scene-based design.
