Noise Critical Issue for eVTOL Acceptance
Industry experts agree that electric drive motors and slower propeller tip speeds will enable eVTOL aircraft to have a significantly lower external noise signature compared to helicopters, but that does not necessarily translate into instant public acceptance.
Juliet Page, a scientist with the U.S. Department of Transportation’s Volpe National Transportation Systems Center, said it is important for eVTOL manufacturers to avail themselves to the variety of integrated, simulated, and dual-use aircraft noise models that have been developed over the years by the FAA, NASA, and the U.S. Department of Defense, as well as the latest advanced acoustics models, in fashioning their aircraft to be as quiet as practicable.
