Since its inception in 1963, aircraft noise analysis has been the Wyle Acoustics Division’s hallmark area of expertise. Wyle’s understanding of the unique aspects of aircraft noise and expertise with existing and next-generation computer models provides a sure foundation for continued work in developing increasingly accurate models of the noise environment in and around airports.
Some of Wyle’s notable work in this area includes:
- Initial development of the computational algorithms for the FAA’s Integrated Noise Model (INM) in the 1970s.
- Since 1985, Wyle has provided ongoing development and refinement of the U.S. Air Force’s NOISEMAP model, the military analogue to INM.
- Development of the new Rotorcraft Noise Model (RNM) for NASA and the U.S. Department of Defense and NATO member countries.
- Development of the Model for Assessing Global Exposure from Noise of Transport Airplanes (MAGENTA) to estimate the global population exposed to noise and the effect of different mitigation scenarios.
- Development of the Aircraft Community Noise Impact Model (ACNIM) to optimize flight tracks to minimize noise exposure.
- Creation of profile customization modeling capabilities for commercial airport operations.
A selection of Wyle services and capabilities includes:
- Basic research to better understand sound propagation and attenuation.
- Development of noise contours using INM, NOISEMAP, NMSim, RNM and AEDT for various operating scenarios.
- Noise measurements and radar data analysis to validate noise contours for FAA Part 150 Programs, and environmental noise studies.
- Strategies for mitigating noise impacts from aircraft operations, including run-up noise.
- Wyle provides additional strengths in land use and GIS, community involvement, noise monitoring systems and aviation operations analysis.
