Hearing is our most important sense for interpersonal communication, yet we have a fragmentary understanding of the basic mechanisms involved in normal hearing. This project addresses the question of how sound location is represented in the brain through the processing of minute time difference with which sounds reach the two ears. The outcome will ultimately enable us to infer how the human brain localises sound, with practical applications for improved virtual auditory realities and hearing aids.

听力是我们人际交往中最重要的感觉，但我们对正常听力的基本机制了解并不充分。这个项目解决的问题是声音位置是如何通过处理声音到达两只耳朵的分钟时间差在大脑中表现出来的。这一结果最终将使我们能够推断出人类大脑是如何定位声音的，并实际应用于改进的虚拟听觉现实和助听器。
