Displacement magnitude and phase angle along radii from the umbo to the center. The images in the upper left are displacement magnitude and phase maps of the motion of a human TM stimulated at 8 kHz and 109 dB SPL. The white dotted lines show the radii used in defining the displacement vs. distance in the other plots. (A) The response to a 5 kHz 90 dB SPL tone. (B) The response to a 8 kHz 109 dB SPL tone.
