Ms. Kompella et Rj. Bernhard, TECHNIQUES FOR PREDICTION OF THE STATISTICAL VARIATION OF MULTIPLE-INPUT-MULTIPLE-OUTPUT SYSTEM RESPONSE, Noise control engineering journal, 45(3), 1997, pp. 133-142
Analytical statistical techniques are investigated for analysis of the
variation of radiated noise from complex built-up structural-acoustic
al systems. The method of moments and Monte Carlo simulation technique
s are identified as the most useful and feasible methods for applicati
on to noise control design, The methods are demonstrated for two avail
able automobile samples, Frequency response function data were measure
d for 98 Isuzu Rodeo sport utility vehicles and for 57 Isuzu pickup tr
ucks, The automobile studies illustrate application of the methods and
interpretation of the results of measurements. In these studies, the
mean, the standard deviation, the cumulative density function, and pro
babilities are computed for single-input-single-output systems, The pr
edicted results are compared to measured results. In addition, the ext
ension of the methods to multiple-input-multiple-output systems is dis
cussed and the bootstrap technique for identifying the sensitivity of
the prediction to the effects of finite sample size is illustrated. (C
