The invention provides an in-vehicle noise reduction system and an automobile, and relates to the field of automobile noise reduction. The in-vehicle silencing system comprises a main controller, a microphone and a headrest silencer arranged in the headrest, and the main controller is electrically connected with the microphone; the microphone is used for collecting noise at human ears, generating a noise signal and sending the noise signal to the main controller; the main controller generates and outputs a first silencing frequency signal according to the noise signal; the headrest silencer generates a silencing frequency corresponding to the noise at the human ears according to the first silencing frequency signal. The silencing frequency can be adaptively adjusted according to the actual noise at the human ears, and the actual silencing and noise reduction effect is better.
本发明提供了一种车内消音系统及汽车,涉及汽车消音领域。车内消音系统包括主控制器、麦克风以及设于头枕内部的头枕消音器,主控制器与麦克风电连接;麦克风用于收集人耳处的噪声,并产生噪声信号发送至主控制器;主控制器根据噪声信号生成并输出第一消音频率信号;头枕消音器根据第一消音频率信号产生与所述人耳处的噪声相对应的消音频率。消音频率可根据人耳处的实际噪音适应性调整,实际的消音降噪效果更好。
