The Estimation of the Time Constant of the Human Inner Ear Pressure Change by Noninvasive Technique

Figure 5

The vertical axis of (a) and (b) is the time constant values, and the horizontal axis is the sinusoidal modulation ( ). The first part “1a” at the top on the resulting curves in (a) is the values calculated from the positive up-going points of ( ) and , “2a” obtained from the positive down-going. In (b), “1b” is obtained from the down-going points of ( ) and , and “2b” from negative up-going pressures. Notice that (a) and (b) are, respectively, Figures 5(a) and 5(b).
