| Research Abstract |
New hearing aid system using bone-conducted ultrasound has been developed for hearing-impaired people. In this study, targeting on the optimal design of the device, precise simulation of ultrasound propagation in medium with microstructure was performed ; as a result, good agreement with measured data was confirmed. The world's first 3-D acoustic model of whole human body created in this study is expected to play important roles in medical engineering and clinical field. Moreover, some required data for practical usage of hearing aid were measured, including the intelligibility of the device under the condition with lip reading.
