摘要：Howling is generated due to acoustic feedback circuit and is difficult to predict since it varies depending on the indoor environment. Furthermore, it is hard to distinguish between original and howling signals in real-time. In this paper, we propose a novel howling detection method based on statistical analysis of temporal power spectra. The proposed method is shown experimentally to be suitable for howling detection.
