EVTOL Noise: What’s Possible? What’s Hype?

Leading eVTOL companies claim that their aircraft can be 10, 100, or even 1000 times quieter than conventional helicopters. Are such low noise levels possible in theory? And what progress has been made and demonstrated so far? To answer these questions, this video reviews the science of sound waves and aircraft noise. It then discusses various noise reduction strategies by eVTOL companies, in particular, patents by Joby Aviation. Finally, noise claims by leading eVTOL companies are analyzed and assessed.
