A Simplified Solid Mechanical and Acoustic Model for Human Middle Ear
Human middle-ear is the key component of the
auditory system. Its function is to transfer the sound waves through
the ear canal to provide sufficient stimulus to the fluids of the inner
ear. Degradation of the ossicles that transmit these sound waves from
the eardrum to the inner ear leads to hearing loss. This problem can
be overcome by replacing one or more of these ossicles by middleear
prosthesis. Designing such prosthesis requires a comprehensive
knowledge of the biomechanics of the middle-ear. There are many
finite element modeling approaches developed to understand the
biomechanics of the middle ear. The available models in the
literature, involve high computation time. In this paper, we propose a
simplified model which provides a reasonably accurate result with
much less computational time. Simulation results indicate a
maximum sound pressure gain of 10 dB at 5500 Hz.
