本研究的目的是生成和比较汽车怠速声音和振动的语义空间，并确定它们的质量维度。在这项研究中，为空转声音(34个属性)和全身振动(22个属性)开发了两组不同的质量属性。与以前的研究相比，结果表明，仅靠声级不足以描述空闲声音和振动感知的复杂性。空转声音和空转振动的质量都具有多维、复杂的特征。结果表明，强度相关属性、基于信号的频谱和时间属性以及基于舒适性和情感的属性都是表征车辆怠速噪声、振动和粗糙度(NVH)性能所必需的。因此，提出了一种基于响度、锐度、粗糙度、波动强度和相对逼近等心理声学指标的指标。结果还表明，情绪方面对声音和振动的评估起着重要的作用。
The aims of this study are the generation and comparison of the semantic spaces of vehicle idling sounds and vibrations and the determination of their quality dimensions. In this study, two different sets of quality attributes were developed for idling sounds (34 attributes) and whole-body vibrations (22 attributes). In contrast to prior investigations, the results demonstrated that the sound level alone is an insufficient attribute for describing the complexity of idle sounds and vibration perceptions. The qualities of both idle sounds and idle vibrations have multidimensional, complex characters. The results show that intensity-dependent attributes, signal-based attributes in terms of spectrum and temporal properties, and comfort- and emotion-based attributes are all required to characterise the idling noise, vibration, and harshness (NVH) performance of vehicles. Therefore, an index was proposed based on psychoacoustic metrics such as loudness, sharpness, roughness, fluctuation strength, and relative approach. The results also show that emotional aspects play an important role for the assessment of sound and vibrations.
