  In part I, spectral moments and kurtosis were established as parameters in
analytic models of correlation and spectral density functions for dynamic
reverberation fields. In this part II, several practical limitations affecting
the accuracy of estimating these parameters from measured stir sweep data are
investigated. For sampled fields, the contributions of finite differencing and
aliasing are evaluated. Finite differencing results in a negative bias that
depends, to leading order, quadratically on the product of the sampling time
interval and the stir bandwidth. Numerical estimates of moments extracted
directly from sampled stir sweeps show good agreement with values obtained by
an autocovariance method. The effects of data decimation and noise-to-stir
ratios of RMS amplitudes are determined and experimentally verified. In
addition, the dependencies on the noise-to-stir-bandwidth ratio, EMI, and
unstirred energy are characterized.
