The current study applied Structural Equation Modelling to analyse the relationship among pitch, loudness, tempo and timbre and their relationship with perceived sound quality. Twenty-eight auditory signals of horn, indicator, door open warning and parking sensor were collected from 11 car brands. Twenty-one experienced drivers were recruited to evaluate all sound signals with 11 semantic differential scales. The results indicate that for the continuous sounds, pitch, loudness and timbre each had a direct impact on the perceived quality. Besides the direct impacts, pitch also had an impact on loudness perception. For the intermittent sounds, tempo and timbre each had a direct impact on the perceived quality. These results can help to identify the psychoacoustic attributes affecting the consumers' quality perception and help to design preferable sounds for vehicles. In the end, a design guideline is proposed for the development of auditory signals that adopts the current study's research findings as well as those of other relevant research. Practitioner Summary: This study applied Structural Equation Modelling to analyse the relationship among pitch, loudness, tempo and timbre and their relationship with perceived sound quality. The result can help to identify psychoacoustic attributes affecting the consumers' quality perception and help to design preferable sounds for vehicles.
本研究应用结构方程模型来分析音高、响度、节奏和音色之间的关系，以及它们与感知音质的关系。从11个汽车品牌收集了28个喇叭、指示器、车门开启警告和停车传感器的听觉信号。招募了21名经验丰富的驾驶员，用11个语义差异量表对所有声音信号进行评估。结果表明，对于连续声音，音高、响度和音色各自对感知质量有直接影响。除了直接影响外，音高还对响度感知有影响。对于间歇声音，节奏和音色各自对感知质量有直接影响。这些结果有助于识别影响消费者质量感知的心理声学属性，并有助于设计更优的车辆声音。最后，结合本研究以及其他相关研究的结果，提出了听觉信号开发的设计指南。从业者总结：本研究应用结构方程模型来分析音高、响度、节奏和音色之间的关系，以及它们与感知音质的关系。研究结果有助于识别影响消费者质量感知的心理声学属性，并有助于设计更优的车辆声音。
