Small Turbine Engine Noise Reduction. Volume V. Data Tabulations
Abstract
Volume 5 of AFAPL-TR-73-79 contains tabulations of the measured engine data developed under the Small Turbine Engine Noise Reduction Study. The data is presented as tabulated listings of the one-third octave band sound pressure level for each engine configuration, each engine load point, and at each microphone position. Sound power level tabulations have also been included, to allow comparison of the effectiveness of the various hardware configurations on the basis of the sound power level. This volume also contains the impedance and acoustic absorption data sheets for those materials and material constructions not reported in Volume 3. In addition, the complete tabulated data from the standing wave (impedance) tube apparatus material tests is presented.
