This is a very mission-specific technology. No, it's really not, there a ton of engineering and scientific uses where it may be useful to measure acoustic emissions off a vibrating surface, but it may be infusible or too resource intensive to attach/deploy conventional acoustic transducers. For example, characterizing sound sources in moving vehicles like trains (which currently require microphone arrays and a lot of post-processing) or wind turbines (which require expensive sound intensity measurement equipment). If the cost of high-speed cameras come down, this could be a valuable alternative.
