The invention relates to the technical field of automobile cabin sound processing, in particular to an automobile cabin sound enhancement system. According to the automobile cabin sound enhancement system provided by the invention, the influence of noise on people is reduced by adopting a noise reduction method, the sound in the automobile cabin is relatively enhanced, and the riding experience is improved. An automobile cabin sound enhancement system comprises a noise sampling module, a noise analysis module, a signal generation module and a noise reduction module, and sound enhancement of a cabin is achieved by reducing noise in the cabin. A noise signal in an automobile cabin is obtained in real time, a noise reduction signal which is the same as the noise signal in frequency and amplitude but opposite to the noise signal in phase is generated under the cooperation of a noise analysis module, a noise reduction module and the like, and noise reduction of the interior of an automobile is achieved according to the principle that opposite-phase waveforms are mutually counteracted. The influence of noise generated in the automobile driving process on the playing content of the playing device is reduced, and the riding experience of people is improved.

    本发明涉及汽车座舱声音处理技术领域,特别地涉及一种汽车座舱声音增强系统。提供一种汽车座舱声音增强系统,通过采用降噪的方法降低噪声对人们的影响,相对地增强汽车座舱内部的声音,提升乘车体验。一种汽车座舱声音增强系统,包括有噪声采样模块、噪声分析模块、信号生成模块和降噪模块,通过对座舱内部进行降噪从而实现座舱声音增强。通过实时获取汽车座舱内部噪声信号,在噪声分析模块和降噪模块等的配合下生成与噪声信号频率和幅值相同但相位相反的降噪信号,利用反相波形相互抵消的原理实现对汽车内部的降噪,降低汽车行驶过程中产生的噪声对播放设备的播放内容的影响,提升人们的乘车体验。
