It is possible to find it with a bit of hardware like a microphone. Very easily by taking multiple level measurement and some multilateration. It gets hard when there is more than one. The problem with identifying it by ear is that you get already some 20-30 cm precision at best unless you've trained in echolocation like some blind people.
For such a small device it could well be a whole room. |
