ASA S12.76 – American National Standard Methods for Measurement of Supersonic Jet Noise from Uninstalled Military Aircraft Engines
This standard describes procedures to measure jet noise from uninstalled military aircraft engines withsupersonic exhaust flows. The methods pertain to propulsion systems mounted on outdoor test standswith appropriate inlets and representative nozzles. Detailed measurement procedures are described fornear-field acoustical characterization. These data can be used to establish baseline noise levels, assesseffectiveness of noise reduction technologies, estimate personnel noise exposure, and provide full-scaledata for refinement of engine noise models. Far-field measurement procedures are described to providedata for estimates of community noise. This standard describes required measurement instrumentation,signal processing, data formatting, and measurement uncertainty. This standard does not apply tocommercial engines, dual-use engines, or other engines covered by FAA/ICAO noise certificationrequirements.
