双耳听觉系统能提供单耳听觉所不能提供的许多效能,其中最重要的是声源定位能力和嘈杂环境中听取和理解所需声音的能力。本研究试图观察:(1)传导性聋是否降低双耳听觉效能。(2)经中耳手术纠正了听阈的双耳听觉效能是否正常。作者采用在噪声环境中双耳效能的掩蔽级差方法(masking level difference
Binaural hearing systems provide many of the benefits that monaural hearing can not provide, the most important being the ability to locate and understand the sound needed in noisy environments. This study sought to observe: (1) whether conductive hearing loss reduces binaural hearing performance. (2) correct the auditory threshold of binaural hearing performance by middle ear surgery is normal. The author adopts the masking level difference method for binaural performance in noisy environments
