| Outline of Final Research Achievements |
MRI (Magnetic Resonance Imaging) is one of non-invasive medical devices and can be used for medical examinations, operations, rehabilitation, and so on. However, MRI generates loud acoustic noise of more than 110 dB in SPL (Sound Pressure Level) because the gradient coil inside MRI device vibrates due to Lorenz force, which is originated from on-off pulse signal into the gradient coil. In this research project, we have developed a head-mounted active noise control system, This system can reduce MRI noise around user's ears and realize verbal communication under loud acoustic noise environments.
