"Sound cannon" capable of disabling drones
Source:
The vast majority of drones and means of individual movement (like gyrometers) to maintain the balance established gyroscopes. These sensors are used in Electromechanical systems, each of which fluctuates at the natural frequency. And recently, experts from the Security company Alibaba, has demonstrated the technology impact sound for the gyroscopes in these devices. The new technology could be used to shoot down drones and disorientation robots.
According to the Arstechnica publication, the authors responsible for creating «sound cannons» Wong, Jingbo and Wang Kang showed how their generator, the sound waves are forced to break down some elements of the iPhone 7 and Galaxy S7. In the course of the demonstration, the researchers showed how the same method disables the DJI drone, virtual reality glasses and a toy robot.
Generator high-frequency sound to disorient «smart» devices
The Authors said they pointed to a number of existing vulnerabilities of equipment and don't plan to create on the basis of their achievements of arms. The more that do it simply. For example, now the electric scooter due to the fairly thick plastic housing do not allow sound waves to penetrate to the sensors of balance. For more serious protection experts offer placed around the sensors and management controllers, sound-insulating layer that prevents the sound of any frequency to reach important components. According to the researchers, these methods of protection should be «gold standard» for «smart» devices, incorrect operation of which can be a threat to human life.
