Scope
Recommendations presented in this document are intended primarily for the acquisition of far-field noise data. The test engine is to be appropriately configured and operated so that the sound pressure levels obtained are consistent with the specific objectives of the test. The principal output of the data reduction system is one-third octave band sound pressure levels. However, when appropriate, data may be recorded for purposes of broader or narrower bandwidth analysis.
Rationale
This document has been updated to reflect current industry test practices and to harmonize technical specifications and requirements with regulatory documentation from the International Civil Aviation Organization.

A-21 Aircraft Noise Measurement Aviation Emission Modeling
To develop and maintain relevancy of recommended practices for aircraft noise measurement and guidance for modeling of both aircraft noise and aviation emissions and to promote a unified technical approach to support the practical assessment of their impact.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
