Yet another application for this tech is indoor localization, where the subtleties of a person's position could still be mapped or tracked, picking up the trail where GPS stopped.
"Big companies, big office buildings, malls and supermarkets that are interested in knowing how and where people walk around are interested in this," Dokmanic said. "Museums could also locate a person inside the building and tell if they're standing next to a piece of art and tailor a presentation."
Combined with the floor plans and blueprints of buildings, the algorithm could be utilized to navigate buildings or large spaces -- complete with vertical, three-dimensional mapping -- where as most GPS devices only provides horizontal, two-dimensional locations.
"If the system knows what the room looks like and knows where the walls are, one microphone will suffice to localize yourself," said Dokmanic. "Then you could image applications like a smartphone app."
Laurent Daudet, a professor who studies acoustic at the Institut Langevin in Paris, says traditionally reverberation can be a nuisance with most studies on localization.
