@Fermiparadox Didn't even know that was a thing, looks cool, wonder if it works well
Coincidentally I heard a small noise today on my car, not sure what it is, looked under the car, pushed the suspensions, did some quick eye examining and didn't see anything
I'm gonna have to observe, see if I'll hear it again tomorrow, and when it happens
@IanC Here are some demos: 1 and 2 of the device. I was also wondering if a similar device can be made that detects the noise-source by finding the time it takes for sound to reach the detectors.
