摘要
为了研究基于汽车主动发声技术的目标声音设计,对3辆应用了主动声音设计(ASD)技术的不同车型汽车即标志4008、宝马i8及奥迪R8进行了车内噪声测试,采集了各个阶次、不同踏板开度及ASD模式下的噪声样本,对采集到的声音样本进行了数据处理和工况分析,基于等级评分法进行了主观评价打分、客观参数计算并建立了多元线性回归模型,以此为依据提出了目标声音设计的流程和方法。结果表明,不同车型汽车的ASD模式对其噪声有不同的影响,阶次特征和踏板开度也会影响其汽车声品质。多元线性回归模型的拟合程度较好,可依此进行声音设计以满足设计目标要求。
In order to study the target sound design based on automobile active sound technology, we test the interior noise of three vehicles with active sound design(ASD) technology, namely logo 4008,BMW I8 and Audi R8.The noise samples of each order, different pedal opening and ASD mode are collected, and the collected sound samples are processed and analyzed, Based on the grading method, the subjective evaluation score, the objective parameter calculation and the multiple linear regression model are established.On this basis, the process and method of target sound design are proposed.The results show that the ASD modes of different types of vehicles have different effects on their noise, and the order characteristics and pedal opening also affect their sound quality.The fitting degree of the multiple linear regression model is good, which can be used for sound design to meet the design objectives.
