An active noise reduction method for a rail transit vehicle and a cab. Structure noise transmission channels of the cab are installed with accelerometers, and air noise transmission channels are installed with microphones; the cab is internally installed with a plurality of secondary sound sources; and the accelerometers, microphones, and secondary sound sources are all electrically connected to an active noise adaptive controller. The method is fused with multi-reference sensor information of the cab, and is able to improve the comprehensiveness and accuracy of reference signal sources, effectively increase the amount of noise reduction in a target noise reduction region, and has a better noise reduction experience and engineering practicability.
