Indoor low-frequency noise control equipment

The invention discloses indoor low-frequency noise control equipment, belongs to the technical field of wireless keyboards, and aims to solve the problems that if two traditional indoor low-frequency noise control equipment needs to achieve a better effect, the thickness and the volume are very large, and active noise control has a limited effect on some high-frequency and complex noises. Through a plurality of modules such as preprocessing, feature extraction, self-adaptive filter design, multi-channel processing, real-time control, output reconstruction and post-processing, the noise can be comprehensively controlled and processed, the sound quality is further optimized, the plurality of modules cooperate with one another, the noise can be comprehensively controlled and processed, the indoor sound insulation effect is provided, and the sound quality is improved. And particularly, a better shielding effect is achieved on indoor high-frequency and complex noise. 一种室内低频噪声控制设备，属于无线键盘技术领域，为解决传统的两种室内低频噪音控制设备若要达到较
