19 the community, FAA, and the aircraft operators into a forum or round table for discussing issues and developing noise management programs. Helicopter Noise Management Program A noise management program is a means to implement the goals of reducing helicopter noise in the community and track the progress toward meeting that goal.

20 Los Angeles has the helicopters broadcasting 1205 or 1206, which makes them distinguishable from fixed-wing aircraft. Where airports or FAA have established voluntary or mandatory helicopter routes, the flight tracking system can monitor and report adherence.

21 literature search for this synthesis found research from agencies such as NASA, university consortiums, and industry about how to design helicopters to reduce noise. However, there is a complicating factor when it comes to quieter helicopter technology.
