Audible P-80 Jet Aircraft Noise

Abstract

The polar distribution, in a horizontal plane, of the acoustic energy generated in the 100-cycle to 10-kilocycle band by a P-80 jet fighter, running at full throttle on the ground, has been measured and analyzed on a constant-bandwidth basis. The data have been used to compute the octave-band levels in the same frequency range, and from these, in turn, overall levels have been computed which check, to within 2 db in all cases, the overall levels actually measured. The formulas and the methods used are discussed in greater detail in appendices.
