(R) Measurement of Far Field Noise from Gas Turbine Engines During Static
Operation
Description / Abstract:
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.
Purpose
The purpose of this document is to describe recommended practices for measurements of far-field sound pressure levels during static operation of gas turbine engines installed on an outdoor engine test stand.
