研究多辆电动车喇叭声同时响起时的听觉烦躁感。
Perceived Annoyance in Multi-source Electric Vehicle AVAS Environments
- 用真实道路录音构建多车声景，模拟真实交通环境。
- 发现多车同时通过时烦躁感显著高于单车情况。
- 适合关注智能交通声音设计与人因体验的研究者。
城市中电动车数量增加导致AVAS声音广泛存在。尽管单个车辆的声音设计与测试常见，但实际交通场景常涉及多车同时出现，其组合可能改变听觉感知，尤其是烦躁感。本研究从单一声源视角转向场景化视角，考察多辆电动车AVAS声音在真实交通环境中的叠加影响。通过双耳听觉测试，使用录制的电动车驶过声音，呈现单车与多车场景，部分刺激模拟车辆从相反方向接近。参与者在每段刺激后评估主观烦躁程度，比较孤立与多车场景下的感知差异。研究揭示了不同重叠程度的AVAS声音对多车驶过时感知烦躁的影响。
原文摘要 · Abstract (English)
The increasing usage of electric vehicles in urban environments has resulted in a widespread presence of AVAS sounds. While individual vehicle sound design and testing is a common approach, real-world traffic scenarios often involve the simultaneous presence of multiple vehicles. Their combined presence may lead to changes in perception, compared to when they are presented individually, specifically regarding annoyance. The work addresses annoyance perception in scenarios involving multiple electric vehicle AVAS sounds. It changes the traditional isolated source-based view into a scene-based one by investigating the combined presence of multiple vehicle sounds as they are experienced in realistic traffic environments. Binaural listening tests were conducted using recorded electric vehicle pass-by sounds. The stimuli presented different traffic scenarios, including single and multiple-vehicles. Selected stimuli were spatially arranged to simulate vehicles approaching from opposite directions. After each stimulus, participants rated their perceived annoyance, enabling a comparison of annoyance responses between isolated and multiple AVAS sound scenarios. The test investigated how different levels of overlapping AVAS sounds affect perceived annoyance when multiple electric vehicles are passing by.
