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

Figure 3

𝑃_𝑖(𝑡) in broken line is the intralabyrinthine inner ear pressure (ILP) or the infrasonic response of the cochlea, and the second curve 𝑃_𝑖(𝑡)−𝑃_𝑐(𝑡) is the modulation of the cochlear signal versus the cerebral fluctuation. We observed a perturbation status in the first 70 points, then after 400 points, these points are rejected from our estimation.
