Dani Blum (2022, “Can Brown Noise Turn Off Your Brain?, The New York Times,https://www.nytimes.com/interactive/2022/09/23/well/mind/brown-noise.html) effectively presents much of the science that underpins Space Doctors discussions of science-based soundscaping, as discussed in this article (also search sounds and soundscaping in our excellent search faciily top right of the website).
Blum’s article, which is well worth reading, also includes links to recordings of different sorts of sounds that can be actively employed to create places where people thrive, mentally and physically.
ps Brown noise is like the sound of a river whooshing by or strong wind.
