Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This will demonstrate the malleability of auditory spatial perception and the impoverished sensitivity of audition during head and self-motion. Knowledge of these distortions will inform applications such as cockpit design, where orienting to auditory signals is common, and other human/computer interfaces.

对刺激的定向经常涉及眼睛和头部的运动。这改善了定位，但带来了随之而来的问题（例如，模糊）。这些问题在视觉上得到了很好的理解，但在听觉上却没有，尽管有证据表明存在共同的神经机制。我们将研究头部运动过程中的听觉（和视觉）定位，表明头部运动会产生听觉抑制和空间扭曲（类似于视觉扫视效应）。这将证明听觉空间知觉的可塑性和听觉在头部和自我运动过程中的贫乏敏感性。这些失真的知识将告知应用程序，如驾驶舱设计，其中面向听觉信号是常见的，以及其他人/计算机接口。
