There is a bit of precedent in Bryan Cantrill's 2008 video of Brendan Gregg shouting at some disks and inducing latency: https://www.youtube.com/watch?v=tDacjrSCeq4 https://www.youtube.com/watch?v=tDacjrSCeq4 (HN discussion last year: https://news.ycombinator.com/item?id=17388144 https://news.ycombinator.com/item?id=17388144) But yeah, a) turning it from simply detecting that loud sound is happening to getting a meaningful audio channel out of the sound and b) treating this as a security concern instead of just a performance one (and flipping the direction of the attack, from sound attacking drive performance to drives attacking sound privacy) is novel, AFAIK.
