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

Figure 1

The following diagram shows the methodology of how the time constant is estimated. The infrasonic waves of the ICP and ILP were filtered from the thoracic and DPOAE signals; each infrasonic wave was between (0.166 Hz, 0.5 Hz), noticed that the reference [26] gives more details about the filter system.
