| Abstract(in English) | In general, bone conduction microphone measuring vibration acceleration is effective for noise. MRI devices are medical device for the tomography image of a human body, it generates the extremely big driving noise of 100 dB or more. Therefore a bone conduction microphone is used for communication in MRI examination, the driving noise propagates to a bone conduction microphone and deteriorates the speech quality. In addition, the MRI driving noise is transmitted through the wall to the control room, and influences the speech quality. Our aim is to communicate the patient’s emergency sign to the doctor using a communication system of the bone conduction microphone in MRI examination. It needs to improve speech quality of the bone conduction microphone. We proposed a noise cancelling system for a bone conduction microphone during MRI examination. In this paper, we investigate the percentage of correct answers of the patient’s voice to improve easiness in speech hearing for the doctor. |
