中文摘要：

骨导超声听觉感知是超声振动通过头骨传导产生听觉感知的一种特殊现象。本文首先介绍了骨导超声听觉感知研究领域的国内外发展现状，在此基础上设计了一套骨导超声听觉感知测试系统并完成了系统的软、硬件平台实现。利用该系统，分别对听力正常和听力障碍被试者进行了主观测试工作，围绕单频超声感知效果及单频可听声、汉语语音由超声载波调制后的感知效果开展研究，比较了多种不同调制方式下的对主观感知效果，并分析了空气传导声对实验结果的影响。

英文摘要：

Bone-conducted ultrasonic （BCU） Hearing is a special auditory phenomenon perceived when a part of human skull is stimulated by BCU vibration. Recent advances of BCU hearing are reviewed. Hardware and software design of a BCU Hearing system was proposed with different carrier frequencies and modulation algorithms examined. We tested characteristics of ultrasonic tones, audible tones modulated by ultrasonic carriers, as well as intelligibility of modulated Mandarin Chinese. System performances were investigated by hearing-impaired and normal-hearing subjects. Acoustic experiments were also carried out in an anechoic chamber to analyze effects of air-conducted sound.
