A third window, which is another cochlear fluid pathway different from the oval window and round window, is considered to be a significant factor in bone-conducted hearing. A three-dimensional finite element model of the human ear consisting of the middle ear and cochlea was used to investigate the effect of the third windows on bone-conducted heraing. This study is aimed to find the third window which causes the consistent cochlear responses with previous studies in air-conducted hearing, and causes the asymmetry of the volume velocity ratio between the oval window and round window in bone-conducted hearing. The preliminary result shows that the cochlear aqueduct and the vestibular aqueduct with high impedance do not affect the basilar membrane velocity in air-conducted hearing. On the contrary, in bone-conducted hearing, the direction of the shaking structure for the bone-conducted stimulation as well as the third window can be a significant factor causing the asymmetry of the volume velocity ratio found by Stenfelt et al.
