论文摘要
改善太空服的大多数努力都是为了增加触觉反馈。但是，声音透明度还可以以相对较低的成本提高情境意识。改进的程度尚不清楚。我们使用福生 - unterberger步进测试来衡量一个人对自我位置的看法的准确性。我们比较了两种情况下的准确性结果：一种听证会受到掩盖的掩盖，其中一个噪声，而不是一个。这些场景分别是声音消声空间西服和声音透明的空间西服的声学代理。结果表明，当应用声音掩盖时，自定位的误差增加了14.5厘米，CI 95％[4.04 28.22]。讨论了将调查结果应用于火星太空服设计的建议。还提供了成本效益分析。
Most efforts to improve spacesuits have been directed towards adding haptic feedback. However, sound transparency can also improve situational awareness at a relatively low cost. The extent of the improvement is unknown. We use the Fukuda-Unterberger stepping test to measure the accuracy of one's perception of self-location. We compare accuracy outcomes in two scenarios: one where hearing is impaired with sound masking with white noise and one where it is not. These scenarios are acoustic proxies for a sound muffling space suit and a sound transparent space suit respectively. The results show that when sound masking is applied, the error in self-location increases by 14.5cm, 95% CI [4.04 28.22]. Suggestions to apply the findings to Mars spacesuit designs are discussed. A cost-benefit analysis is also provided.
