At first I thought this was click bait, too. But actually.. TL;DR take: Hospitals and labs contain deadly pathogens in regions of lowered air pressure. Sophisticated electronics monitor pressure and control the evacuation system accordingly. Many such spaces have resonant frequencies in the audio range. Ergo, it's possible to play specific tones through an entertainment system to establish significant deviation from the average pressure to fool the sensors, and disrupt the containment. Such tones could be embedded in pop music. Wow.
