Holly Smith-Dalenberg of NASA’s Human Health and Performance Directorate shows participants of the human systems integration meeting an International Space Station mock-up as part of the Acoustics Lab tour (from left, Liz Warren of Blue Origin, Curtis Lee of Vast, Jamie Barrett of the Federal Aviation Administration, and Vast’s Caroline Kim and Leilani Bautista.) A spacecraft like the International Space Station contains a large number of complex systems – all with their associated fans, pumps, valves, and other mechanical noises. To mitigate the risk of excessive noise, all flight hardware is required to pass acoustic emissions testing.
