We've told you time and time again NOT to take pot shots at drones. Doing damage to someone else's property is almost always illegal. On top of that, firing guns into the air is one of the most dangerous things you can do. But there's another weapon that can be deployed against some drones: sound.
According to Computer World, researchers have discovered that resonance - the vibration caused by sound - can mess with a drone's gyroscope if the gyroscope is using a resonant frequency in the audible spectrum. And if your drone's gyroscope, which keeps its "balance," is thrown off, the machine is likely heading for the ground.
The sound required to screw up a gyroscope has to match its resonant frequency. When South Korean researchers hit the correct frequency in a test, the drone came down.
The researchers were testing sound interference on the drones by attaching a wireless speaker to them. Still, they reported that at 140 decibels, a drone could be vulnerable from up to 40 meters away. There aren't any drone sound-guns on the market yet, but manufacturers of the gyroscopes could negate the potential problem by insulating the gyroscopes with foam or other shielding.
