Can you also do the opposite with this, and isolate sounds from a specific direction, even if there is a lot of noise coming from other directions? Listening to a specific server in a big server room, for example?
yes, it is called reciprocity! basically radar works that way (but using EM wave, instead of soundwave). and yes, you can use the same principle to generate sound (instead of receiving) to a specific direction. it is beamforming, I wrote a thesis about it.
Can i buy one ?
Very cool.
How i can made one at home?? Bro

fucking awesome dude
are there any cellphone apps that allow to locate noise source, with gps say ?
You have an enormous amount of wasted redundancy by placing the microphones in a regularly spaced grid.
