Negative Pressure Room is a technical-legal-sanity requirement for biolabs or infectious-control hospitals to prevent pathogens being leaked out. Now an attack is demonstrated to fool the sensors into turning it off ... with specially crafted sound. Scary? https://arxiv.org/pdf/2210.03688.pdf
Very interesting security research. "attacker can play the malicious music using public radios. If individuals place their radio near a pressure port, ... a good chance that the attack will be effective ... intentional leak of deadly microbes from NPRs may result in bioterrorism"
