The invention relates to a vehicle and a noise reduction method. The vehicle comprises a vehicle body, a cabin, a noise reduction assembly and a processor. The cabin is arranged in the vehicle body. The noise reduction assembly includes a noise collector for collecting noise sound waves from the cabin and a sound wave emitter for emitting offset sound waves. And the processor is electrically connected with the noise component. And the processor receives and processes the noise sound wave to obtain a noise phase, and controls the sound wave emitter to emit the offset sound wave to the cabin according to the noise phase. Wherein the counteracting phase of the counteracting sound wave is opposite to the noise phase.
