It can determine the specific location of survivors based on the small differences in the sounds heard by each ear. If the survivor can no longer speak, just tap with your finger and make a slight noise that can also be heard by it. Even if the people buried under pressure are trapped under a fairly solid large-area cement floor, as long as the heart still has a slight trembling, the detector can feel it, so the rescue team can determine if anyone is alive under the rubble.
