We have developed an examination system for spatial hearing using the virtual reality technology. In the examination for sound localization, virtual sound source (pink noise) located eight directions (every 45 degree) around the subjects were simulated based on the standardized HRTF (head related transfer function). In addition, the examination to test the effects of the position of noise in the signal detection ability in noise, which is well-known as "cocktail party phenomenon", were also made up using the same technique as the above-mentioned system.These system was tested with the subjects with normal hearing as well as impared listeners. Results obtained suggests that the ability on the spatial hearing can be effectively examined using the virtual system. These system appeared to be very useful for the clinical applications in that these system can be prepared relatively easier than open-field system..

我们利用虚拟现实技术开发了一个空间听觉检测系统。在声源定位检测中，根据标准化的HRTF（Head Related Transfer Function）函数，模拟位于被试周围8个方向（每隔45度）的虚拟声源（粉红噪声）。此外，还利用与上述系统相同的技术，对噪声中噪声的位置对信号检测能力的影响进行了测试，这就是众所周知的“鸡尾酒会现象”，这些系统在听力正常的被试者和不敏感的听众中进行了测试。结果表明，该虚拟系统可以有效地检测空间听觉能力。这些系统似乎对于临床应用非常有用，因为这些系统可以比开放场系统相对容易地制备。
