While the cicadas taking over the East Coast may just seem like a bother or a tasty snack for your dog, researchers at the Naval Undersea Warfare Center are studying how such a tiny animal can make such a loud noise in the hopes that they can borrow the technology to improve underwater sonar. The researchers from Newport, R.I., presented their findings Monday at the International Congress of Acoustics, Popular Science reported. Researchers hope that by mimicking the cicada’s method of making sounds, small unmanned underwater vehicles will be able to use active sonar systems, which today are too large…
