在物理和感知两个方面 ,评价噪声环境下使用耳背式助听器双麦克风的自适应波束形成器的言语理解效果 ,这是首次应用这种运算法则进行的大规模实时配戴的测试。主要的感知研究是针对 :①干扰声的频谱 时间特性 ;②干扰声环境 ;③听力障碍 ;④助听器麦克风的基本构型这四个方面 In terms of physics and perception, this paper evaluates the speech comprehension effect of the adaptive beamformer using two microphones of aural hearing aids in noisy environments, which is the first large-scale real-time wear test using this algorithm. The main perceptual research is aimed at: (1) spectral temporal characteristics of disturbing sound; (2) disturbing acoustic environment; (3) hearing impairment; (4) basic configuration of hearing aid microphones
