Sound-transparency-Koh-Block-test

Extra-Vehicular Activity and Intra-Vehicular Activity spacesuits block external sound. This induces sensory deprivation, a side effect is lower cognitive performance. This can increase the risk of an accident. This undesirable effect can be mitigated by designing suits with sound transparency. If the atmosphere is available, as on Mars, sound transparency can be realized by augmenting and processing external sounds. If no atmosphere is available, such as on the Moon, then an Earth-like sound can be re-created via generative AR techniques. We measure the effect of adding sound transparency in a suit by means of the Koh Block test. The results indicate that participants complete the test more quickly when wearing a suit with sound transparency.

舱外活动（Extra-Vehicular Activity, EVA）与舱内活动（Intra-Vehicular Activity, IVA）专用航天服会阻隔外界声响，进而引发感觉剥夺效应，其副作用为认知表现下降，这会提升事故发生风险。该不良影响可通过设计具备声音透传功能的航天服加以缓解。若存在大气环境（如火星场景），可通过增强并处理外界声响实现声音透传；若缺乏大气环境（如月球表面），则可借助生成式增强现实（Generative AR）技术重建类地球环境的听觉体验。我们通过科赫积木测试（Koh Block Test）评估航天服搭载声音透传功能的效果，测试结果显示，佩戴具备声音透传功能的航天服时，受试者完成测试的速度更快。
