ANC（Active Noise Control）降低声场中的噪声。一般来说，ANC系统需要始终将麦克风放置在您想要降低噪音的位置。因此，ANC不能在远离麦克风的地方实现足够的降噪性能。已经提出了一种虚拟感测技术，以减少在没有误差麦克风的退出区（ZoQ）中的噪声。然而，传统的虚拟麦克风无法跟踪非平稳路径。在本文中，我们提出了一种具有虚拟感知的ANC来跟踪ZoQ和麦克风之间的非平稳路径。
ANC (Active Noise Control) reduces noise in an acoustic field. In general, the ANC system needs to always place a microphone at the location where you want to reduce noise. Therefore, the ANC cannot achieve sufficiently noise reduction performance far from a microphone. A virtual sensing technique has been proposed to reduce the noise in a zone of quit (ZoQ) where there is no error microphone. Unfortunately, the conventional virtual microphone cannot track the nonstationary path. In this paper, we propose an ANC with virtual sensing to track the non-stationary path between ZoQ and microphone.
