Not a single microphone but there is acoustic vector sensor which can also give you the sound's direction. Very expensive though, several Israel companies use them for detecting gunshot's direction.

- loxias 5y agoDo you know anything about these "acoustic vector sensors"? When I first saw a popular science article about them, I got excited about incorporating them into an array, but couldn't find any technical details, just a lot of what looked like vaporware. Is it anything more than three orthogonal pressure sensors? (aka.... 3 microphones?)

- dendrite9 5y agoMicroflown makes one, it uses very small temperature differences. You can look for acoustic particle velocity sensor to find more about how they work. I can't remember the paper, otherwise I'd provide a better link. https://www.microflown.com/products/standard-probes https://www.microflown.com/products/standard-probes This PDF may be helpful http://past.isma-isaac.be/downloads/isma2010/papers/isma2010_0607.pdf http://past.isma-isaac.be/downloads/isma2010/papers/isma2010...
- loxias 5y ago_temperature_ differences. Ah. Thanks for that paper, it's enlightening.
