| NOISEMAP 7 |
NOISEMAP is a computer program used to model noise exposure in the vicinity of a military air base due to aircraft flights and engine run-up activities. Noise contours generated by NOISEMAP are used in support of the Air Installation Compatible Use Zone (AICUZ) program and National Environmental Policy Act (NEPA) documentation. The Air Force Research Laboratory (AFRL/RHCB) oversees the development and maintenance of NOISEMAP and its related programs.
NOISEMAP 7 is the latest version of the NOISEMAP software. It is a Microsoft Windows application and contains a suite of programs including the input component (BASEOPS), the noise calculation component (NMAP), and the output component (NMPlot). NOISEMAP can be used in conjunction with the Rotorcraft Noise Model (RNM) and the Federal Aviation Administration's Integrated Noise Model (INM).
Download and installation: instructions for the most current version of NOISEMAP 7 can be found at the Wasmer Consulting website http://www.wasmerconsulting.com/baseops.htm.

| NMPlot |
NMPlot is a Microsoft Windows application designed to view and edit georeferenced scalar data sets (grids). The development of NMPlot was sponsored by the United States Air Force and the United States Federal Aviation Administration to produce contour plots for their airport noise models. While the program was designed to support noise models, it can just as easily process data from other types of models or from sources other than computer models. NMPlot can read and write NMGF files, produce contour and color gradient plots, apply mathematical transformations to the data, combine two or more data sets, and interface with GIS systems. For using NMPlot with NOISEMAP, the program is packaged within the NOISEMAP 7 software. However, since NMPlot can be used separately with other applications, for a stand-alone version, download and installation instructions for NMPlot can be found at the Wasmer Consulting website.

Rotorcraft Noise
Model (RNM) |
Rotorcraft Noise Model (RNM) was developed by the NASA Langley Research Center and Wyle Laboratories to calculate noise exposure specifically from helicopters and tilt-rotor aircraft such as the V-22 Osprey. Public distribution of RNM includes a set of noise hemispheres for the Canadian Forces CH-146 (BELL 412SP). Sound hemisphere sets for other aircraft may be available from NASA or the DoD.

| Military Operating Area, Military Training Routes & Range Noise Model |
| MR_NMAP |
The Military Operating Area and Range Noise Model (MR_NMAP) calculates noise levels from subsonic aircraft operations on Military Training Routes (MTRs), Military Operating Areas (MOAs) and Special Use Airspaces (such as ranges). The noise levels are output as contours or in tabular format, and are suitable for inclusion in Environmental Impact Statements (EISs) or Environmental Assessments (EAs) in support of the National Environmental Policy Act (NEPA).

| Sonic Boom Noise Model |
| PCBOOM |
PCBOOM is a computer program that calculates the location and magnitude of sonic-boom overpressures on the ground due to supersonic flight. This Microsoft Windows application is intended for environmental planners and engineers who may need to estimate the noise impact from individual flights of supersonic military aircraft. Output for printer, plotter or screen includes tables of overpressures and graphic display of the sonic-boom overpressure footprints on the ground. The footprint plots show the location of all ray positions that exceed overpressures of a given level. Flight track, Mach number, and altitude profile plots are also provided.

| Single Aircraft Noise Calculators |
| SELCAL |
SEL Calculator or SELCal is a Flyover Noise Calculator that estimates the noise levels generated by a single aircraft flyover. It is primarily designed for research purposes, but is applicable for field use. This is an update of the USAF's MS-DOS version of Menu 10 also known as "Flyover" but with added features. The primary noise-calculating engine remains OMEGA10 and the noise database is NOISEFILE (the aircraft database in NOISEMAP and MR_NMAP). Both OMEGA10 and NOISEFILE have been updated for this program.
