Methods and systems for diminishing the effects of an acoustic signature of vehicles
Methods and systems are provided for diminishing the effects of an acoustic signature of a vehicle while the vehicle is en route to a destination. One method includes the steps of retrieving acoustic data representing an acoustic model of the vehicle, terrain data representing a terrain model of a geographic area surrounding the destination, route data representing a model of a plurality of routes to the destination, and weather data representing atmospheric conditions of the geographic area. The method also includes selecting a route to the destination based on the acoustic, terrain, route, and weather data. A system includes means for performing the retrieving step and the selecting step of the above method. Another system includes memory storing the acoustic, terrain, route, and weather data, and a processor coupled to the memory and configured to select a route to the destination based on the acoustic, terrain, route, and weather data.
