Figure 6: Mean global RMS shear strain normalized by RMS excitation pressure for each subject. Mean RMS shear strains for each subject, normalized by input RMS pressure, are shown in Figure 6. At 45 Hz, the global strain amplitude in subject S008 is significantly higher than subjects S013 and S014. On the other hand, at 80 Hz the global strain amplitude is approximately equal across all subjects. Figure 7: Mean regional RMS shear strain normalized by RMS excitation pressure, all subjects (n=3). Error bars signify one standard deviation. (Outset) Regions 1-3 are color-coded for each subject. Mean regional RMS shear strains, normalized by input RMS pressure, are shown in Figure 7. At 45 Hz, the strain amplitude reaches 217 μİ per Pa of applied pressure in the outer ring of this imaging plane; at 80 Hz the response is approximately 58 μİ per Pa, reflecting reduced transmission. 63
