Currently, noise pollution is a topic of considerable interest, especially near airports and vertiports. To assess the impact on a nearby community, Environmental Impact Studies and Land Use Planning Assessments require estimates of the noise footprints that will be generated by aircraft using a facility. Measuring the noise footprints directly for every aircraft under numerous operating conditions would be extremely expensive.
Comparisons show good agreement, helping to validate the prediction model.
It is a tool for predicting ground noise footprints generated by rotorcraft. RNM can predict the ground noise footprint for complex flight profiles if given the noise characteristics of a vehicle under a variety of operating conditions. RNM can also be used as a research tool to design flight procedures for noise abatement. The adverse impact on a community adjacent to a facility can be reduced by tailoring flight procedures to minimize the noise exposure at given locations around the facility.
