Outer and Middle Ear Model

Evan Shenkman

Circuit Model

The above circuit models the physiological effects of the outer and middle ear on sounds as it enters the ear.

The two plots below show the frequency response and phase response of the model. The green line shows the input; the light blue line shows the output of the outer ear; the yellow line shows the output of the middle ear. I believe the effect of the middle ear is practically non-existent because the input impedance of the middle ear model is not properly matched to the output impedance of the outer ear model. I will test each model individually and expand this report.
