摘要
针对某特种车辆驾驶室声品质问题进行分析。通过试验采集不同行驶工况下的驾驶室内不同测点的噪声,对心理声学客观评价参数(响度、尖锐度、波动度和粗糙度)进行了分析。在特种车辆驾驶室室内噪声综合评价基础上,得到该特种车辆在各工况下响度值过高的结论。最后通过频段滤波分析找到该特种车辆驾驶室主要噪声频段。
Aiming at the interior sound quality problem of a special vehicle,the sound quality analysis was carried out. With sound signals of key parts in the operator cabin being acquired under various vehicles driving condition,the psychoacoustics objective evaluation parameters were analyzed in detail such as loudness,sharpness,fluctuation and roughness. Based on the comprehensive evaluation of interior noise of the special vehicle,it was concluded that the loudness level is over high under various conditions. Lastly,by means of filtering analysis method,the main frequency band of interior noise was found.
