| Research Abstract |
MRI noise was very loud, and it exceeded 100dB. The development of ear protection system by adaptive control for the subject of such an acoustic environment is an important task. First of all, to develop the ear protector, the location of the microphone that considered the characteristic of the sound source of the MRI acoustic noise for the adaptive control was examined. In addition, the production of soundproof protective device that used this result and the performance by the computer simulation were examined.
