This could have multiple uses. One that I can think of is to have a profile of what a normal sounding manufacturing floor is or lathe, mill, any machine that operates. If the sound profile changes you might be able to distinguish what component is failing on that machinery. This could possibly be extended to listening to organisms or ecosystems like the human biome to identify problems. I know other tech might exist in this but I find the possible uses for this fascinating.

There's quite some research, and even some products (I mentored a company about five years ago doing such a thing, but I even forgot their name, and don't remember what their outcome was) about this topic. - https://www.hindawi.com/journals/js/2018/4105208/ https://www.hindawi.com/journals/js/2018/4105208/ If memory serves, you don't even need to have permanently installed sensors, you can do it with a portable stethoscope kind of contraption which can detect anomalies and help to schedule preventative maintenance.
