Noise measurements taken in cabin of Convair 880 show that boundary layer excitation is controlling source determining cabin noise environment; curve representing generalized boundary layer excitation, derived from in-flight noise measurements plus fuselage wall transmission characteristics obtained from laboratory tests, has proven useful in predicting changes in cabin noise levels resulting from variations in flight conditions.
