Researchers mapped out the dimensions of this room using only a snap of the fingersImagine walking into a room, snapping your fingers, and instantly knowing the exact size and shape of that room, in all three dimensions, accurate down to a few millimetres.
This is the latest development from a team of American and Swiss researchers, who have developed a computer program that only needs four microphones and a snap of the fingers in order to return the size and shape of a room.
"Our software can build a 3D map of a simple, convex room with a precision of a few millimeters," PhD student Ivan Dokmanić said in a statement.

"Each microphone picks up the direct sound from the source, as well as the echoes arriving from various walls," he added. "The algorithm then compares the signal from each microphone. The infinitesimal lags that appear in the signals are used to calculate not only the distance between the microphones, but also the distance from each microphone to the walls and the sound source."
