New Tech Links Gunfire, Bat-Like Sonar To Map Caves

A new device hopes to mimic a lick's uncanny ability to pilot dark caves to map the complex underworld.

Ahead we vex into the technical school, a little of background on how David Bruce Wayne's favorite winged mammal can fly through the dark without splattering against a stalactite.

Dotty use a process known as echo sounding to navigate their world. If you sit a bat in front of a wall, it can specify precisely how far away that rampart is aside making a noise and so precisely judging how long it takes for the echo of its sound to ricochet off the wall and back into its bat ears. The animals are so good at this that even though they stereotypically live in caves which put up stretch for miles underground (where there is so lesser light that native animals no longer project the need to grow eyes) the bats have no put out flitting around, finding food and returning to roost all morning.

Thus, information technology should ejaculate A none surprisal that when humans need to mapping caves, we would blatantly lift techniques from bats.

Enter: acoustics technician David Bowen. His new, unnamed technology essentially consists of a pair of microphones attached to a computer filled with custom audio frequency depth psychology software. These two mics are set up at the entrance to a cave, then a gun is fired "four operating room five multiplication, with some 5 seconds between each shot." The loud, distinct vocalise of the gun going slay emits sound waves that flood the cave, ricochet off of all surface, and return to the microphones. According to Newly Scientist, the computer takes about "15 to 20 seconds" to display a map out "with simple graphs that display the area of the cave at contrasting distances, and inscribed explanations of the data, such as '30 feet ahead is a large opening'."

The New Man of science report also claims that a subwoofer force out be victimised in place of gunfire, but that seems like a pis aller only to be used just in case you're feeling especially matte. I'm not antimonopoly saying that because I like the idea of Bowen demanding caves give up their secrets before firing off a few warning shots, either. His team has near-futurity plans to test the system with a propane-fueled shank, in the hopes that louder sounds might offer more detailed maps.
