文中对自适应抗噪声送话器进行了实验探讨，比较、讨论了滤波器阶数、步长、采样频率以及主输入传声器和参考输入传声器的相对距离、位置和声场对控制效果的影响，指出了距离、位置等和相干性有关的因素是影响控制效果的主要因素。并通过实验证明，自适应抗噪声送话器大大提高了语言的可懂度。 In this paper, the adaptive anti-noise microphones are discussed experimentally, and the influence of the filter order, step length, sampling frequency and the relative distance, position and sound field of the main input microphone and reference input microphone on the control effect are discussed. Factors such as distance, location and coherence are the main factors that affect the control effect. Experiments show that the adaptive anti-noise microphone greatly improves the intelligibility of the language.
