(a) Acoustic pressure distribution in middle ear cavity predicted by the FE model at frequency of 1000 Hz. The sound pressure applied at the canal entrance was 120 dB SPL (20 Pa). The color bands represent different pressure levels relative to the canal entrance pressure. The external ear canal was hidden. (b) Acoustic pressure distribution in middle ear cavity predicted by the FE model at frequency of 8000 Hz. The sound pressure applied at the canal entrance was 120 dB SPL (20 Pa). The color bands represent different pressure levels relative to the canal entrance pressure. The external ear canal was hidden.
