A vision for Urban Air Mobility (UAM) acoustic modeling and sound visualization in the presence of background noise, leveraging the Advanced Acoustic Model (AAM) is provided for the consideration of UAM ecosystem participants. The growth of the UAM ecosystem is fostered by Uber via the Elevate Summit 2017 in Dallas, Texas. Acoustic Modeling Tools provide the flexibility to design vehicles while considering acoustic footprints, population impacts and operations. Example of AAM modeling of a conventional helicopter and a notional NASA VTOL vehicle in the presence of ambient background sounds are presented. Existing databases of US National noise utilizing the Bureau of Transportation Statistics database are utilized. Opportunities and areas of collaboration within the acoustic measurement and modeling community and the UAM vehicle and operational designers are presented. Specific model improvement and tool set interoperability recommendations as well as new vehicle acoustic technologies to foster community acceptability of unique VTOL designs are provided.
