中文摘要：
为了在人耳处获得更大范围的静音区，对基于虚拟传声的单通道有源头靠系统进行了改进。在静音区（人耳处）设置2个虚拟传声器，采用基于虚拟传声器技术的filtered—Xleastmeansquare（FXLMS）算法，控制目标区域内的残余误差信号，以实现对人耳处噪声信号的抑制，扩大静音区的范围。仿真结果表明，在静音区设置2个虚拟传声器可以有效降低静音区的噪声信号，并能扩大有源头靠的静音区范围。
英文摘要：
In order to obtain a larger quiet zone at the human ear, the improved single-channel active headrest system based on virtual microphone control is presented. Two virtual microphones are positioned in the quiet zone. The FXLMS algorithm is used to control the residual error signal within the target area, thus significant attenuation of the noise signal and larger quiet zone at the human ear can be achieved. The simulation results show that setting two virtual microphones in the quiet zone can reduce the noisy signal in the quiet zone effectively, and expand the scope of the headrest＇s quiet zone.
