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.
