摘　　要：在分析啸叫信号特征的基础上,研究了6个能够体现啸叫信号特性的频率和暂态特性参数。同时,探索和实践了联合使用2个以上参数来进行啸叫检测的方法。测试数据表明,在进行啸叫抑制时,使用多参数联合啸叫检测的方法,能在有效抑制啸叫的前提下,减少其对正常信号的损伤。Based on the analysis of the characteristics of howling signal,six frequency and transient characteristics parameters which can reflect the characteristics of howling signal are studied.At the same time,the method of using more than two parameters to detect howling is explored and practiced.The test data show that the method of multi-parameter combined howling detection can effectively suppress howling and reduce the damage to normal signals.

关 键 词：陷波器 啸叫抑制 啸叫检测 快速傅里叶变换(FFT)
