几个数组处理算法的实施和评估有经验的助听器用户。该阵列由四个定向麦克风组成，侧面安装在听众头顶的头带上。该算法包括两个自适应阵列处理算法，一个固定的阵列处理算法，和一个参考条件组成的双耳定向麦克风。在具有一个和三个独立噪声源的条件下对算法进行了评估。性能指标包括定量的语音接收阈值和定性的受试者偏好评级的易用性，使用配对比较程序测量。平均而言，固定算法提高了2 dB的语音接收阈值，而自适应算法提供了7-9-dB的参考条件的改善。判断易听性的受试者通常更喜欢所有的数组处理算法，而不是参考条件。结果表明，这些自适应算法应进一步评估在更现实的声学环境。(C)2003年美国声学学会。
Several array-processing algorithms were implemented and evaluated with experienced hearing-aid users. The array consisted of four directional microphones mounted broadside on a headband worn on the top of the listener's head. The algorithms included two adaptive array-processing algorithms, one fixed array-processing algorithm, and a reference condition consisting of binaural directional microphones. The algorithms were evaluated under conditions with both one and three independent noise sources. Performance metrics included quantitative speech reception thresholds and qualitative subject preference ratings for ease-of-listening measured using a paired-comparison procedure. On average, the fixed algorithm improved speech reception thresholds by 2 dB, while the adaptive algorithms provided 7-9-dB improvement over the reference condition. Subjects judging ease-of-listening generally preferred all array-processing algorithms over the reference condition.. The results suggest that these adaptive algorithms should be evaluated further in more realistic acoustic environments. (C) 2003 Acoustical Society of America.
