What began as an idea for a senior research project is now a fully-functional device that really has the Internet talking.
Engineering students Seth Robertson, 23, and Viet Tran, 28, from George Mason University in Virginia invested about $600 of their own money into developing a “somewhat portable” device that can put out fires with low-frequency sound waves.
Tran explained to the Washington Post that sound waves are “pressure waves, and they displace some of the oxygen” and at the right frequency, those waves can separate the fire’s oxygen from the fuel.
“The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting.”
Initially, the duo assumed high-frequency sound waves would prove effective in dousing a fire. Instead, low frequencies did the trick.
“But it’s low-frequency sounds—like the thump-thump bass in hip-hop that works,” Tran told the university’s website.
