About AAM
The Advanced Acoustic Model (AAM) is a suite of software tools that allows users to model vehicle sound levels at receiver positions, either on a uniform grid or at specific defined locations, from helicopters, tiltrotor vehicles, and fixed wing aircraft.
AAM is flexible in its ability to allow users to model noise from any traditional or evolving transportation noise source.
