Abstract

With powertrain electrification, the character of a vehicle's soundscape significantly changes. Not only does it become quieter, but also the so far dominating combustion engine broadband noise, which shaped people's expectations, disappears. With the upcoming technology, we are empowered to create soundscapes with novel frequency spectra and sound design approaches. Vehicle soundscapes are dynamic by nature due to load and speed changes, and the driving situation. In this study, different active sound design concepts for electrified vehicles (EVs) have been assessed by N = 83 participants concerning their conveyed impressions of Perceived Innovativeness, Liking, and further relevant dimensions. The sound design concepts are varied in their general sound character and level of innovativeness and then presented in a listening laboratory. By employing the Repeated Evaluation Technique (RET) in the context of sound design research, we gather insightful data about dynamic effects in the perception of innovative acoustic textures in the context of active EV sound design. The findings of this study reveal dynamic effects in novelty perception and aesthetic preference, as well as insights into the semantics specific design characteristics convey. This can be helpful in shaping the character of a vehicle, making predictions about long-term appreciation of novel driving sound concepts, and assisting sound engineers and designers in creating innovative yet appreciated sound designs for EVs.

回到未来:电动汽车声音设计的创新性。
随着动力总成的电气化,汽车声景的特征发生了显著变化。它不仅变得更安静,而且迄今为止主导人们期望的内燃机宽带噪音也消失了。有了即将到来的技术,我们有能力用新的频谱和声音设计方法来创造音景。由于负载和速度的变化,以及驾驶情况的变化,车辆声景本质上是动态的。在这项研究中,N = 83名参与者对不同的电动汽车主动声音设计概念进行了评估,包括他们对感知创新性、喜欢度和其他相关维度的印象。声音设计概念在其一般声音特征和创新水平上各不相同,然后在听力实验室中进行展示。通过在声音设计研究的背景下使用重复评估技术(RET),我们收集了关于主动EV声音设计背景下创新声学纹理感知的动态效应的深刻数据。本研究结果揭示了新颖性感知和审美偏好的动态效应,并揭示了特定设计特征所传达的语义。这有助于塑造车辆的特性,预测对新颖驾驶声音概念的长期欣赏,并协助音响工程师和设计师为电动汽车创造创新且受欢迎的声音设计。
