Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejon, South Korea, seem to have found an easy way to take out drones from the sky using ‘the right sound’. They explained that some components inside drones are vulnerable to certain frequencies, so with the right one, you can disable them.

One of the researchers stated that components such as gyroscopes have been made to resonate with sound above the audible spectrum, but some of them are still in the audible spectrum, which makes them vulnerable to interference. In an experiment, they used a speaker attached to a drone and connected to a laptop via Wi-Fi. When the right sound was played through the speaker, the drone dived down and crashed.

Of course, you won’t be able to physically attach a speaker to a drone in most cases if you want to make it crash, but this proves that sounds can be used to crash drones. Other experiments involved attaching a speaker to a police shield and making a sonic wall, but without the proper high-tech equipment to keep aim on the drone while it spirals out of control, it is useless.

The conclusion is that drone enthusiasts shouldn’t worry about it, unless your neighbour silently attached a speaker to your drone. Using high-tech sound disruptors, as far as I know, is illegal in most countries, so if you’re not piloting a high-tech military drone, you should be fine.
