这项研究表明，通过打开和关闭人类耳廓，我们可以改变人类感知的声音方向。每只耳朵独立地转换为 100% 打开、50% 打开和 100% 关闭状态，并对这些耳朵转换的所有 9 种组合进行了测试，以评估对围绕受试者 180 度放置的 7 个扬声器输出的声音的感知方向。我们证明，通过使耳廓变形，我们可以改变对声音方向的感知，或使其变得虚幻。我们还发现，除了 7 个扬声器中的 1 个（或声音方向）之外，100% 关闭扬声器声音来源一侧的耳朵以及 50% 关闭扬声器另一侧的耳朵往往会对声音的感知方向产生最大的改变。
This study demonstrates that by opening and closing the human pinna, we can change the direction of sound perceived by humans. Each ear was independently transformed into a 100% open, 50% open, and 100% closed state, and all 9 combinations of these ear transformations were tested to evaluate the perceived direction of the sound output from 7 speakers placed 180 degrees around the subject. We demonstrate that by deforming the pinna, we could change the perception of the direction of sound, or make it illusory. We also found that except for 1 out of 7 speakers (or directions of sound), closing 100% of the ear on the side of the speaker where the sound is coming from and 50% of the ear on the other side of the speaker tends produce the most alteration to the perceived direction of sound.
