Unmanned air system (UAS/UAV) noise and urban mobility noise were the subject of two National Academy of Engineering (NAE) hosted workshops under the auspices of the Technology of Quieter America (TQA) program. Both workshops were organized by the INCE Foundation in cooperation with the U.S. National Aeronautics and Space Administration (NASA) and the U.S. Federal Aviation Administration (FAA). The first workshop UAS and UAV (Drone): Noise Emissions and Noise Control Engineering Technology was held in Washington, DC in December, 2018. manufacturers, users, U.S. government agencies, universities, consultants and professional societies. The second was an e-workshop Aerial Mobility: Noise Issues and Technology in December, 2020. Participants at each workshop included representatives from manufacturers (US and international), users, U.S. government agencies, academia, consultants, professional societies, and law firms. Topics included: modelling, testing, psychoacoustics, community impact, noise reduction strategies, measurement techniques, and uses of both UAS/UAVs and aerial mobility.
