Abstract(in English) Magnetic resonance imaging(MRI) device makes tomography for medical diagnosis. It generates a loud driving sound. A communication system using a bone conduction microphone and the speaker was proposed by us. The communication quality decreases because of two kinds of noise. One is acoustic echo by bone conduction speaker, and the other is vibration by MRI driving sound. We propose a quality improvement technique that an acoustic echo canceller considering fast velocity of vibration propagation and a shielding of the microphone. This paper showed that the communication quality of the bone conduction microphone improves by the proposal technique.
