SoundLoc System Could Save Energy

Jul-27-14 The SoundLoc system is able to detect indoor positioning using echolocation, which could help to cut energy costs in large buildings by identifying unoccupied rooms.

Previously, using echolocation in this manner required specialized equipment that could still be confounded by background noise. The new system, however, is able to ignore the noise by processing the signal in a particular way—allowing the data to be gathered using a standard laptop. In tests, the team used a laptop to create a set of sound waves and then listen for the echo. After sampling 50 locations, they processed the data to create an echo fingerprint of each room, and claim they can identify an individual room with a 97.8 percent accuracy.

The team envisions the system being used to identify unoccupied rooms in order to turn off unneeded devices such as lights or heat.
