Fan/Compressor Noise Research. Volume 3. Compilation of Test Data
Abstract
Appendices A-C contain the processed data from each test vehicle configuration, in the form of the computer print-out sheet. The acoustic data presented on these sheets consists of 1/3 octave sound pressure level at each angle and 1/3 octave sound power level for frequencies of 50 to 10K Hz, overall sound pressure level and perceived noise level at each angle, overall sound power level, and the directivity index. A detailed explanation of the terminology is presented in the following pages. All data has been corrected for standard day atmospheric absorption conditions. The data for D/V I (Appendix A) is at a 250 foot radius only; the data for D/V II and D/V III (Appendices B- C) is at both a 250 foot and a 150 foot radius.
