The shape of a room can be modelled using echoes produced from sound, new research has found.

Like bats who emit sounds in order to navigate, researchers can now plug sounds into a computer algorithm to map a room.

The team were able to build a full 3D image of a room using four microphones to record echoes bouncing off walls.

Writing in the journal PNAS, the researchers say the technology could one day help solve crime.
