Chinthaka Premachandra and Mr. Yugo Kinasada from Shibaura Institute of Technology, Japan, developed a novel artificial intelligence (AI)-based noise cancelling system. The system generates a similar sound as the UAV noise and then substracts that sound from the sound captured by the onboard microphones. This can be immensely useful in searching for victims in collapsed houses and rubble in the aftermath of natural disasters like earthquakes.
