Abstract: Recently, MRI scanner is continually used for medical diagnosis and many biomedical researches. When it operates, however, intense noise is generated. The SPL (Sound Pressure Level) of the noise approaches 130dB especially in 3T MRI. It is expected to increase because the strength of magnetic field will increase for higher-resolution image. It's a safety risk because it interferes with communication between operator and patient and could cause hearing loss to patient in extreme case. For this reason, active n…
