| Outline of Final Research Achievements |
We recruited subjects for able-bodied men based on the human engineering experimental commission approval and the simultaneous measurement experiments of the right and left ears in pulse wave data were carried out for each subject presented the switching of some sounds.
Advanced biomedical signal analysis focused on relations between the ears in the pulse wave data was able to extract the asymmetry index to reduce the errors.
The measurements of light exercise yielded almost regular pulse waves in the both ears, which can be interpreted as resulting from steady blood flow. On the other hand, the measuring results presented some sounds revealed pulse wave fluctuations, which suggest the difference between the left and right.
