The invention provides a mobile noise detection method and system, a storage medium and electronic equipment, and the method comprises the steps: obtaining a target sound signal collected by a microphone disposed on a subway train when the subway train runs on a target track; and performing abnormal feature extraction on the target sound signal, and when at least one abnormal feature value is extracted from the target sound signal, determining each abnormal feature value as a noise point of the target track. Through a non-contact indirect detection mode, the track noise detection efficiency can be improved.

    本发明提供了一种移动式噪声检测方法、系统、存储介质和电子设备,所述方法包括:当地铁列车在目标轨道上运行时,获取设置在所述地铁列车上传声器所采集的目标声信号;对所述目标声信号进行异常特征提取,当从所述目标声信号中提取到至少一个异常特征值时,将每个异常特征值分别确定为所述目标轨道的噪声点。本发明通过非接触式的间接检测方式,能够提高对于轨道噪声检测的效率。
