The purpose of this study was to determine the effect of stimulus intensity on heart rate response in 18 low-risk human fetuses between 37 and 40 weeks gestation. Each fetus was stimulated in quiet sleep with a 30-s voice sound at intensities of 80 dB and 90 dB. The fetal cardiac electrical signal w

β¦ Synopsis
Statistical predictions for the mean value and variance of both power input and power transmission in acoustic systems are presented which include the effect of variable modal decay rates. The newly derived models indicate that the variability of both characteristics is expected to increase with increasing decay rate variability while predicting the effect. Results from numerical experimentation are presented which confirm both the expected variability increase in power transmission and the presented models' ability to qualitatively and quantitatively capture the increase.
